Poor Poor Service TELKOM to a Loyal customer.

I had some ***** done on my banking account so the account was closed I went a Telkom shop on the 24 of April to change banking details and also made a manual payment of R352 I was then billed end of May R41 not knowing the reason why,as my bill was supposed to be R372.Got a sms from Telkom Thursday the 9th June to say I am in arrears of R1121 which I did not understand on the 10th I contacted them where I was told my account was in arrears of R371 which I have never been in arrears before I asked them who billed me R41 I am not working in your billing department I then paid on the 12th June R400 on the 15th June Telkom debit my account with the amount of R721.No 1 I have a debi check mandate to be debit the last day of the month I have not gave them Authority to debit my account.I asked twice yesterday and today to be contacted by a Manager still no feedback.I was also charge R200 for unpaid debit.I as thinking to cancel this contract an move to another network they are chasing away a loyal customer bad bad service
