Very poor service from Telkom

First of all I am so disappointed, very furious, I am just so unpleased with how Telkom treats us as customers. I have had an account with Telkom for more than 6 years and I have never ever experienced such a terrible service that I have experienced with them like this year!! Their consultants are just very rude and inconsiderate of their customers needs. In August I had called Telkom to inform them that I wanted to change my banking details to a new bank account because I was no longer using the old one but they refused to do so because they said that my new bank account needed to be 3 months old before I can change it. They then submitted a debit order on an account that I already informed them that I am no longer using just so it can bounce then they get to charge me a R202 rejection fee because TELKOM just enjoys reaping their customers off, whom have been loyal to them for so many years!! I paid it! Then they did the same thing the following month, debited on an account that I clearly informed them that I am no longer using, charged me Again !! And I paid it! While it was not my fault that they submitted a debit order on an Account that I CLEARLY stated that I am no longer using!! Then I finally got to submit my new banking details then they repeated it again!! Submitted a debit order on an inactive bank account. I then called in, one of your consultants ( I am not going to mention any names coz my intention is not to get anyone into trouble, but I know their names) told me to make a payment manually then she said that she will submit a proof of payment for me just so they must not charge me the following month, but they did. On the 4th December I called in to find out why they charged me, its a pity I forgot the lady’s name who was assisting me. The way she was so mean she showed no interest in my concern as a customer and even went as far as telling me that I didn’t even request for my banking details to be changed. Today on the 5th I have called in to enquire about it again, then another lady assisted me. She started being helpful and was was also being impatient as time went on. When I said I wanted to dispute the rejection fees she told me they won’t be able to dispute it for me. I asked her to transfer me to her supervisor then she asked me why as if I had no right to speak to her supervisor. When she finally transferred me around 18:17 I waited for the supervisor to take my call until the phone went quite, not sure if she transferred me knowing very well that the supervisor might have knocked off already but still transferred me anyway!!!! I am very disappointed in Telkom and how their consultants take us for granted!!! I am definitely taking my account elsewhere because Telkom just reaps us off for no reason and their service has just become so terrible, even in the branches they are just as terrible !!!! I am so tired of Telkom!!
