NO RESPONSE from credit controller

<p>I have been trying to do an upgrade of my contract since friday 2 December 2016 at the MTN store in Kolonade Pretoria. The system gives an error message which means my credit limit must be increased. The contract i want to take out will be much cheaper than the on e i currently have with Mtn. The store has sent numerous emails to the credit control department, to LESEGO TSELE, and this person just do not respond to the emails !!!!!!!! Everytime its just an automated message saying they will respond within 8 hours. This has been going on since friday 2 December. Do you think this is 8 hours????? Really!!!!!!! If this person does not want to do their job rather give the job to someone who is interested in doing their job properly. Ref number of emails is ********** 4 and my account number is C ********** . Really people please wake up!!! This is not the way to treat paying customers. I have always been an Autopage client and was forced to migrate to Mtn, and this is the way i get treated.</p>
