Double Charged and No credit

Vodacom failed to deduct from my account which led my account into areas. I took upon myself to pay the amount of R750 for three months consecutively. To my Suprise Vodacom never allocated the R2250 amount I paid. After I paid Vodacom suddenly deducted the whole amount I owed to them which I had already paid in three months. I went to my bank to try and reverse the money and I was told they can’t reverse it I must contact Vodacom to do the reversal. I have done that and submitted my bank statements to Vodacom to date my money is not returned nor credited. They still continue to deducting from my account like nothing is wrong.

I have never been so disappointed by a service provider.
