Debit order

August 2017 my account was debited with R2031 extra which was paid back into my back account end of Sept. Beginning of October I app**** for a loan at my local bank but because of a R6400 debit from Vodacom the bank declined the loan saying my living expenses is to high. They suggested I get a letter from Vodacom stating that it was a fault and their side and that my account was wrongly debitted. I first phoned on Tuesday 03/10, after speaking to exactly 5 persons I was told that someone will phone me within 24h. Needless to say I'm still waiting, I phoned again on Wednesday and to my surprise was told that no request or quiry was logged. After explaining again I was again told that the legal dept will phone me in 24h. Needless to say, once again..... nothing and I'm still waiting. My qeustion, what the hell has this got to do with the legal dept, the collection dept and who ever I was redirected to. Is there nobody at Vodacom that can use a computer, type a letter and push the send button. I have never been in arrears on my account, even when they debited the wrong amount I accepted it as a human error and did not complain. Now I had to suffer the humiliation of being declined a loan and nobody wants to take responsibilty. In the mean time, a loan which I needed 2 weeks ago is on hold because of Vodacom's poor service delivery. You should be ashamed!!! I am a paying customer and expect service and feedback because of your incompetence.
