Terrible Client Service

For any one who is considering taking up a contract with telkom I would strongly advise you to think twice. I have been with telkom for 18 months and truth be told their service to date has been terrible. A few months ago I found out about telkoms online payment system that one could use for paying the invoice amounts due on my contract. I started using it in September but noticed that after making payments they would still try debit my bank account and I was charged what they call a "payment rejection fee". When I queried this i was told that I should make my online payments prior to my invoice due date because the online payments take 48 hours to reflect. Ever since then I have been making my payments before the invoice date and yet I am still experiencing the very same problem. In November I paid my account on the 23rd mind you this is way more than the 48 hour period I was told about and yet my invoice for December was showing the rejection charge. Same applies to the invoice I've received this month, I made my payment on the 28th yet there is a rejection fee dated the 1st of January. What frustrates me most is that before the payment I had called to ask if they could update my banking details as this situation was frustrating me, the lady I spoke to told me that she could not do it, maybe i should try go in the branch but because I did not have the time I opted to just pay the account online but it seems like a system that is meant to be convenient for clients is turning out to be more of a nightmare for me. I just spoke to one of the agents and he says to me that they have been prompted to advise clients to pay 10 days before because the 48 hour period is not working. I must this has been a huge frustration and disappointment, firstly due to the lack of consistency in the distribution of information towards clients. Secondly in the fact that when I asked the agent why they couldn't change my banking details he said that they could and I was given the wrong information, which makes me wonder if this was not done purposefully just so they can continue to add exorbitant charges to my account. Either way the service is awful and I have even decided that I will be canceling my contracted and moving to different network.
