TELKOM OVERCHARGING MY ACCOUNT

A few months back i set up a debit order of R400 with Telkom because of the internet package which i took. The debit order was set to go out on the 1st of every month. Telkom debited account on the 29th of every month and charged me a R200 penalty fee. My account has been up to date thus far but they are charging me an amount of R937.05 for the month of April. I refused to argue or over the phone with the call centre agent as Im exhausted of always explaining myself and requesting updated statements after payments have been made and proof of payments being sent to them. They do not pick up my conversation with the agent i spoke to when i requested my debit order date to be on the 1st. If Telkom cannot solve my problems i will drop them as a telecommunications provider as this contributes to unnecessary problems and stress. It is not my fault that Telkom does not have a record of the conversation of my debit order conversation and therefore should have not charged me penalty fees. This is 1 of the many problems i've had with this company to date. Telkom should assist me with this problem ASAP instead of us,being valued customers always waiting for them.
