Unfair

I fell behind on payments because vodacom stopped my debit order after a payment did not go through which I didn't realize until they stopped the service. Phoned customer care who transferred me to legal department. Asked the lady how to rectify the problem, told me I must pay R756 to have my account rectified and will be back on within 24hours. Made the payment with a reference nr that she sent me. Vodacom then allocated to money to an account that I had with them and last used in 2008. Thereafter my sim card was deleted and now I have to pay R105 for a new sim card and R285 for reactivation. This was in a sense my fault because I didn't check my bank statement but I strongly feel this is their mistake as well and now I have to doc up money for the new sim. They do not want to admit that the allocation of the R756 was their mistake and consequently led to my sim being deleted.
