Glacfar le míreanna a fhillfear laistigh de 40 lá ón dáta a fhaigheann tú na hearraí. Ní féidir míreanna saincheaptha a fhillt nó a mhalartú. Ní féidir míreanna a ceannaíodh le cárta bronntanais leictreonach a fhillt; ní bhaineann aisíocaíochtaí leo.
Bronntanas Saor in Aisce
Fáilte go Roymall, do shuíomh gréasáin gairmiúil chun bronntanais ollmhargaidh préimhe a cheannach. Táimid thar a bheith buíoch as do thacaíocht, agus ba mhaith linn ár mbuíochas a chur in iúl trí bhlas breise spraoi a chur le do cheannacháin. Nuair a cheannaíonn tú linn, ní hamháin go mbaineann tú taitneamh as táirgí ar ardchaighdeán a fheabhsaíonn do stíl mhaireachtála, ach gheobhaidh tú bronntanas saor in aisce eisiach le gach ordú a chuirfidh tú. Réidh chun iniúchadh a dhéanamh ar ár mbailiúchán agus na bronntanais foirfe a aimsiú? Déan iniúchadh ar ár rogha earraí ollmhargaidh préimhe, cuir d'ordú, agus bí ag súil le spraoi do bhronntanais saor in aisce ag teacht in éineacht le do cheannach.Polasaí Loingseoireachta
Oibreoimid go dian chun earraí a sheachadadh chugat tar éis d'orduithe a fháil agus a chinntiú go sroicheann siad slán sábháilte. Soláthrófar sonraí seachadta i do ríomhphost deimhnithe.I bhformhór na gcásanna, déantar orduithe a phróiseáil laistigh de 2 lá. Faoi imthosca speisialta, déanfar moill air mar seo a leanas: Nuair a chuireann tú ordú Dé Sathairn, Dé Domhnaigh nó laethanta saoire poiblí, déanfar moill 2 lá air.De ghnáth, teastaíonn 5-7 lá oibre (Dé Luain go Dé hAoine) gan a bheith faoi thionchar moill eitilte nó tosca comhshaoil eile.Toisc go bhfuil ár seirbhís loingseoireachta ar fud an domhain, beidh amanna seachadta ag brath ar do shuíomh, mar sin d'fhéadfadh sé go mbeadh cúpla uair ag teastáil agus fan go foighneach má tá tú i gceantair nó tíortha iargúlta.1. Polasaí Fillte & Malartaithe
Glacaimid le míreanna a ceannaíodh ar roymall.com amháin. Má cheannaíonn tú ónár ndáileoirí áitiúla nó miondíoltóirí eile, ní féidir leat iad a fhillt orainn. Ní ghlactar le míreanna díolacha deiridh nó bronntanais saor in aisce le fillt.Chun bheith incháilithe le fillt, ní mór do mhír a bheith gan úsáid agus sa chéad chaoi a fuair tú í. Ní mór í a bheith sa phacáistiú bunaidh freisin.Tar éis treoracha fillte a fháil uainn, déan do mhíreanna fillte a phacáistiú agus do phacáiste a scaoileadh ag oifig an phoist áitiúil nó ag seachadóir eile.Déanfaimid do mhír fillte nó malartaithe a phróiseáil laistigh de 3-5 lá oibre tar éis dúinn í a fháil. Déanfar an t-aisíoc a phróiseáil agus a chreidiúint go huathoibríoch chuig do bhunmhodh íocaíochta.Ní féidir aon fhillt nó malartuithe a ghlacadh má táirgeadh an táirge go saincheaptha, lena n-áirítear méid saincheaptha, dath saincheaptha, nó cló saincheaptha.An bhfuil cabhair bhreise uait, déan teagmháil linn. service@roymall.com nó Whatsapp: +8619359849471
2. Polasaí Aisíocaíochta
Gheobhaidh tú aisíoc iomlán nó creidmheas siopa 100% tar éis dúinn an pacáiste fillte a fháil agus a sheiceáil. Déanfar an t-aisíoc a phróiseáil agus a chreidiúint go huathoibríoch chuig do bhunmhodh íocaíochta.Tabhair faoi deara nach bhfuil costais loingseoireachta agus aon dleachtanna nó táillí incháilithe le haghaidh aisíocaíochta. Ní féidir na costais loingseoireachta breise a aisíoc nuair a sheoltar an pacáiste. Tá tú freagrach as na táillí seo a íoc agus ní féidir linn iad a aisíoc nó a aisíoc, fiú má fhilltear an t-ordú ar ais chugainn.Nuair a fhaighimid agus a dheimhnímid do mhír fillte, seolfaimid ríomhphost chugat chun a chur in iúl duinn go bhfuairimid do mhír fillte. Cuirfimid in iúl duit freisin faoi cheadú nó diúltú d'aisíocaíocht.Má tá aon fhadhb agat maidir leis an bpróiseas aisíocaíochta, déan teagmháil linn. service@roymall.com nó Whatsapp: +8619359849471Features:
