Poor customer services

I have an account with Ackermans, and I paid my account on the 1st November through EFT. On the 4th I received an SMS that my account was not paid, but I thought maybe the money would still reflect on their side. When I received the statement, I realised that the payment was not showing, and then I called Ackermans customer services on Monday the 21st. After being taken from pillar to post, with every consultant that I got giving me different instructions on what to send to Ackermans for my payment to recorded on my account, I eventually spoke to one who told me that the problem with my payment could be that I had used the account number as reference instead of the card number. He asked me to send emails again with a letter explaining the predicament. The last 2 emails that I sent (after sending 4 emails) were sent to *** and *** with 3 attachments, i.e. my ID copy, typed letter (on Word), and proof of payment. I called this morning, my account is still NOT updated- reason: THEY HAVE NOT RECEIVED ANY OF MY EMAILS??? I SENT AGAIN THIS MORNING. I KNOW THEY WILL NOT RECEIVE THEM BECAUSE I HAVE SENT THEM TO THE SAME EMAIL ADDRESSES THAT I HAVE BEEN SENDING TO. BOGGLES MY MIND THAT WITH ACKERMANS THE CARD NUMBER AND ACCOUNT NUMBER ARE NOT LINKED. I GUESS I HAVE TO LIVE WITH FACT THAT I HAVE A 'MISSED PAYMENT' THAT HAS BEEN PAID INTO A USELESS ACCOUNT NUMBER. SHEER INCOMPETENCE AND LACK OF CUSTOMER CARE OR SERVICE. YOU CAN DO BETTER THAN THIS, ACKERMANS CUSTOMER SERVICE!
