MTN services

I have made an R800 payment in August through internet banking into MTN's account.After making the payment they never loaded it into my account and had to go back to a branch and pay another R800.I have tried multiple times trying to contact customer care by MTN and even till today no one has ever answered the phone.I have send an email through asking if they have received it and sent an POP.They rep**** back saying they received the payment and will load it into my account.After a month I went back to a branch and asked them if they can assist me into finding out what happened to the amount I paid through via EFT.They said that there isn't any money paid.I went then to my bank and asked if the payment went through.After getting confirmation from the bank that there was a payment made I went back to MTN asking if they can please assist me and sort out my account.At the Branch they told me that they will load the payment into my account.At that time it has already being 3 months after this EFT transaction.NOW we are on month 4 and it's still not loaded into my account after multiple times I've tried to contact customer care and visiting the branch and no one has fixed this issue.I ALSO asked if they can please move they debit date at the beginning of the year and still it's not being done.This is honestly very poor service and would like to have this issue fixed please
