Lack of customer care

On the 23rd December 2017 i bought USB ultra flat cable (Energizer) at Vodacom shop in Menlyn in Pretoria. I used the charger for less than a month , it was no longer working. On the 24th of January 2018 i took it back and was told that the manager was not available i should come back today 25 January 2018. I did exactly that and on my arrival at Vodacom Shop in Menlyn, the lady that assisted me went n call a lady by the name of Zodumo Njenjani, who was extremely arrogant. This lady Zodumo was accusing of damaging the cable and bringing it back. She said she cannot help me as when she give me the cable was not broken. I tried to explain her what was happening n she could not listen I was not happy with her the way she handled this enquiry. Her arrogance and accusation made me leave the shop very sad and disappointed. No 1 i paid for a cable which have a 2 year warranty and when i exercise my write to receive the service i deserve ,Zodumo told me that she wont refind me or replace the cable as i damaged it No 2 my problem is the arrogance of the lady who did not even want to listen to my side of story. No 3 is that i was send back yesterday as the manager was not at work which means she left with the shop hence i was send back to come back when she was there. I used my time, my money and my efforts only to be treated with disrespect by Zodumo. I will never do business with Vodacom shop in Menlyn. They render bad service and Zodumo had bad attitude
