6 Months and they still can't get it right

We went to the Telkom shop in northgate to take out another contract only to find that he system says that we are in ares on our account. For the past 6 months we have had nothing but endless issues with the billing department that has no idea on how to do there jobs, the end of each month is a massive frustration for me having to deal with people that have no idea on how to do there job. It is a massive surprise to me that such incompetence is tolerated in any business. Every month they do not take the debit order of our account then i do a transfer for the amount send the proof of payment through and then round about the 15th of each month a debit runs for R1050-00 which i have to try and get back only to be told that they can not find this money and i have to be inconvenienced further by having to go to the bank and get a stamped copy of the statement to send through. I would like you to pull up the last 6 months recorded conversations and use it for training purposes to show your staff how not to do there jobs, I find the service from your company completely useless and disappointing. and what i have typed her is only a small part of what incompetence we have had to deal with.
