MTN no response

Been a loyal subscriber since the Autopage days, then handed off to MTN directly when Autopage ceased to exist. Calling 135 and asking to be put through to either credit department and/or retentions I wait on the phone for 45 minutes before putting the phone down in frustration. Using the webform to send a query to retentions ....and no reply EVER What a useless bunch of twits and I will be gladly moving my business over to your competitors very soon
