WE ARGUE OVER INSIGNIFICANT ISSUES, IT'S TIRING

On the 08 February made a purchase and received an sms notification. The subsequent transaction was on the 15th of the same month, the credit available is not tallying, called the client services this morning and the consultant was busy talking to over me and did not want to give me a chance to explain my side so that we can reach a common ground. I had to cut the call short to avoid an unnecessary altercation. I informed this ill mannered person that the credit available in my phone was the actual credit that i could use for purchases. She was telling me that the credit available that they send me is not the actual credit at my disposable, simple question I posed to her was should I need to make a purchase looking at the credit I have and I get to the pay point, then the transaction fails what then? My card has never worked like that even if I can have R3.00 credit I would go to the shop an make a purchase of the very R3.00 and it has never declined, so what has changed. Bad attitude and being defensive to answer a question has never been viewed as customer service. Get your act in order.
