السلام عليكم
ممكن مساعده يا شباب
البارحه استلمت كام ريس حق الدراجه واسم الكام Webcams . وهاذي الرساله من عندهم ويقولون :
Core Requirements
If you did not send your cam for processing and purchased core cam , you may return a stock cam for a core refund . All cam cores must be returned within six months of purchased. Although the lobes of a hardwelded cam are totally re-worked , the rest of the cam is not. In order to receive a full core refund, you must return a good core, a copy of your original invoice, and it must be received within 6 months of your invoice dare.
... واكون شاكر لكم
