Bad Customer Service/Pathetic processes

My CX was thrown out of the window this morning. I will never recommend this company to any of my family and friends. on the 29 May i had funds available on the MobiMoney that i can withdraw, funds where never deposited into my account. I again went to my APP on the first and withdraw again the money never got deposited. My worry is that when i withdraw my installment changed. Called in on the 21 June to find out what happened and never got assistance, called again this morning spoke to a lady by the name of Ndileka who refused to give me her surname and she said its personal she can give her surname. what i wanted was a confirmation that i am not going to be debited for funds that i didn't receive. She told me that she can send me that confirmation via email as she doesn't have access to emails even the Team Leader doesn't have access to emails i just have to take her word for that.

Cant wait to finish this contract.
