Telkom baywest

I had a WiFi contract with Telkom for two years then it was changed to month to month .I went to a baywest branch end of June and enquired about cancelling.the gentlemen that help me said I need to come into the branch before the 5th of july because there won't be any deductions then.this is what I did I went to the branch again on 29th of June and a different person cancelled my contract I asked for a second time if there would be any deductions and he said no.he gave me a reference number and said my contract was cancelled.on the 5th of July Telkom tried to debit my account with R499 which was my premium.when I queried it the manger from that same branch said it js because they work in arrears and i didnt pay yet for June months usage.this is absolutely ridiculous I asked twice if there was going to be deductions and waa told no.i an so unhappy and disappointed I never missed a premium and they just take my money I have called customer services and they said they will take it up with the branch that was a month ago and still nothing.today again two amounts was deducted from my account again telkom.i never gave authority for this and also i am not able to reverse it .I am extremely upset i will never take out any contract or anything at telkom ever again.till this day is till haven't received the 499 back and they just keep deducting money from me.this is outrageous ,unfair and wrong .they are basically *****ing my hard earned money.
