Vodacom Shop In Westwood Mall Zero Service Excellence

Last i bought a power bank for R1000 cash at Vodacom Westwood Mall. The power bank worked whilst i was at the shop but stopped working after three days when i got home. I returned the item for a refund and the Manager assured me that i would get my refund as soon as his Head Office has responded on the email he has sent regarding the power bank being faulty as other power banks in the shop could not be used for replacement as all could not work either. He asked me to come back after a week of which i did and when i came he hid in his Office and sent his sales assistant that i could not get a refund and can buy anything in the shop for the same value. My God what could i buy because i wanted a power bank wherein theitr power banks were faulty and wanted a refund so i could purchase the power bank elsewhere. We kept on arguing with the sales assistant until i finally letf the power bank in the shop without getting my refund either, but they lost a customer because i have never returend to that Vodacom in Westwood Mall and will never ever spend my money in that shop again. Just warning everyone out there about Vodacom Shop in Westwood Mall
