Polîtîkaya barkirinê
Em ê piştî wergirtina fermanên we ji bo şandina tiştan bi xebatê bigirin û pê ewle bin ku ew bi ewlehî têne. Agahiyên şandinê dê di e-nameya weya pejirandinê de were dayîn.Di piraniya rewşan de, ferman di nav 2 rojan de têne sepandin.Di şert û mercên taybetî de, wê wiha dereng bibin: Dema ku hûn fermanê di şemî, yekşem an jî înên giştî de bidin, dê 2 roj dereng bibin.Normal, ew hewce dike 5-7 rojên kar (ji duşemê heta înê) bêyî ku ji hêla derengiya firînê an faktorên din yên hawîrdorê ve were bandor kirin.Ji ber ku karûbara meya şandinê li seranserê cîhanê ye, ji ber vê yekê dema şandinê dê li gor cihê we be, ji ber vê yekê heke hûn li navçeyên dûr an welatan in, hûn hewce ne ku hinekî bisekinin.
1. Polîtîkaya Vegerê & Guhertinê
Em tenê tiştên ku ji roymall.com hatine kirin qebûl dikin. Heke hûn ji belavkerên me yên herêmî an firoşgehên din bikirin, hûn nikarin wan li vir vegerînin.Tiştên firotanê yên dawî an diyariyên belaş ji bo vegerê nayên qebûl kirin.Ji bo mafdarî ji bo vegerê, tişta we divê nehatiye bikar anîn û di heman rewşê de be ku hûn wê wergirtiye. Divê ew di pakêta xweya orîjînal de jî be.Piştî ku hûn rêwerzên vegerê ji me wergirtin, ji kerema xwe tiştên xwe yên vegerandî pakêj bikin û pakêta xwe li postexaneya herêmî an kuryeyek din bihêlin.Em ê tiştên we yên vegerandî an guhartî di nav 3-5 rojên karkirinê de piştî ku em wê wergirin, bisekinin. Veger dê bixweber li ser rêbaza weya orîjînal a dayînê were kredî kirin.Tiştên ku bi awayekî xweser hatine çêkirin, di nav de mezinahiya xweser, rengê xweser, an çapa xweser, nayên vegerandin an guhertin.Heke hûn hewceyê alîkariyê bin, ji kerema xwe bi me re têkilî daynin. service@roymall.com an Whatsapp: +447549870296
2.Polîtîkaya Vegerê
Hûn ê piştî ku em pakêta vegerandî wergirin û kontrol bikin, vegerê tevahî an 100% krediya dikanê bistînin. Veger dê bixweber li ser rêbaza weya orîjînal a dayînê were kredî kirin.Ji kerema xwe bînin ku lêçûnên barkirinê û her qebzeyek an xerc nayê vegerandin. Lêçûnên zêde yên barkirinê piştî ku pakêt hat şandin, nayê vegerandin. Hûn berpirsiyar in ku hûn van lêçûnan bidin û em nikarin wan bêpar bikin an vegerînin, heta ku ferman ji me re were vegerandin.Heke pirsgirêkek bi prosesa vegerê hebe, ji kerema xwe bi me re têkilî daynin. service@roymall.com an Whatsapp: +447549870296
u2666 Adopt the Direct Digital Synthesizer (DDS) technology and provide stable, precise, pure and low distortion signals.
