Poor customer service assistance with payment problem

I am very dissappointed by the service from cell c to resolve a query. On 5 Feb I made a payment to my one account and accidentally added a digit to the reference number. After realising my mistake, I emailed them the proof of payment explaining the whole issue. I received a mail back that said they would contact me within 72 hours. I am still waiting for that call. Then my services was suspendid and I made another payment on 4March and phoned them. They said I should call the next day as this was already late and was a matter only collections department could resolve. On 5 march explaining the matter again and was promised the issue will be resolved. Now today, 14 March, again my services have been suspendid. Phone them again and boy oh boy, they just keep telling me I am in arrears and suddenly I have 3 accounts and need to email collections department to request a funds transfer from one account to another. Now what about the previous R270 that was paid on 5 Feb? Is anyone going to look where that money went? Should I just write it off and accept it lile loadshedding and sitting without water? NO!!! Resolve this Issue Cell C. I have been a cell c customer for more years than i can remember and now you dont want to help me. I pointed out the mistake but obviously no one cares to go check on the bank statement and assist to rectify. If it os not the shop that has an excuse of they cannot assist with payment because they are just a franchise then it is customer service people that dont listen to the problem and assist to resolve it.
