Terrible Experience with Telkom

I have taken out a telkom contract in mid may for an LTE data deal,Expecting a debit to go off on the 1st of july for the amount i was told and confirmed i would be debited. 1st july i was debit an amount over the actual confirmed amount. Trying to get through to the call centre is DREADFUL they are not helpful and when i asked to speak to a manager they apparently have NO MANAGERS im appalled and fraustrated and they have still not sorted out my query!I hipe some person who can actualky sort my query out calls me!
