Poor service with Telkom

I have had bad service from Telkom. I have been debited an irregular amount on my current contract for the past couple months. I am enquiring as to why this is, unsatisfactory responses from Telkom Via Email and no one can give me a straight answer. As a last resort went to the Telkom Store in Rosebank which needless to say was a waste of time to say the least, the staff were very rude and couldn't care less about identifying a problem, then to be told the accounts department will call me and if I miss there call they will not call again, I was standby all day to receive the call and no call. I think that its extremely unprofessional that the accounts department calls once and if you miss the call, tough luck they will not call again. Long story short my overall interactions with Telkom was below average and very frustrating as well as the staff at the Rosebank branch who were extremely rude and basically doing me a massive favour actually helping a customer.
