VODACOM AGAIN

After numerous attempts to get my account sorted out, I am now asking or help via this channel. I have sent mails to a lady at the following email address, ***, who promised to sort out the problem with the accounts department. She was very helpful, but afterwards NOTHING happened. I used the incorrect account number and that being the reason I sent proof of payment. Account is still in arrears, getting letters of demand, and all because someone, somewhere is not doing his or her work. CAN WE PLEASE GET THIS SORTED ONCE AND FOR ALL??????
