Why can no one help me !!!!!

I have cancelled and paid up an old account more then 6 months ago . This account is still showing overdue and is ruining my credit record

I cannot seem to even get to a consultant because the only Vodacom number I have is no longer on contract and therefore I cannot get through.

How exactly am I supposed to resolve these issues when I cannot even call the call centre .

This needs to get rectified immediately!!!! This has gone on too long . How many times must one person send a ****ing proof of payment before one of you people actually do your job
