Vodacom refuse to give money of additional payment made

I took out a new cellphone contract with vodacomjan 2018. On specific day I was requested to pay R 105. I paid it in the shop. Vodacom then again tried to debit my account with an additional R 55. due to the fact that I only get a sassa income there was no funds in my account on the day of the debit, I was also not informed to keep mentioned amount in my account for the debit... this result into additional charges on my bank account and vodacom charged me an additional fee. Second debit order was done for double contract amount... I was never informed that I will be charged if debit order was declined. I enquire to vodacom regarding the debits on my account in February... only then was I informed ito the set charge. By this time I’ve already paid more than 150 on bank charges as well. I went to vodacom to sort this... I paid the outstanding 406 only to find on debit order run I was charged same amount, again I enquire to vodacom requesting that they should refund me as I have paid now double.

I was informed that my payment was credited to another account i **********

Up to date I received no refund from vodacom only to find that I was charged again until end of March. I have medical expenses to pay and need that refund urgently.. the lady at the call center was not helpful at all, she gave me attitude not giving me a chance to explain. Being a customer for more than 20 years I feel unvalued and will not recommend vodacom as a service provider. Ref I ********** 3 accno.
