Complaining of telkom

I had 3 contracts 2 wifi and other one was a mobile I've been using telkom for 4 years but the experience that I have with them this year was so depressing paying my installment from Jan till march without services when I call them having to deal with different consultants who had no solution at all ,everytime when I call I have to explain the story all over don't know if their system don't keep records, my 1st installment paid on 31 Jan by eft they couldn't pick up the payment then I've send proof of payment to them more than ten time ,everytime they will say wait for a week after a week it's another story passed Jan, febr same story now have to pay febr also without services then they were claiming that they don't see my payment for Jan again have to send the proof of my payment again and wait for 14 days still I need to pay for March in order to have the services paid March now I was waiting for the service nothing called again they told me the system canceled all my contracts now they want all the money for the mobile how ,but with all this struggle since I've been receiving sms that says your case is resolved you will receive services as soon as possible. Don't know how does telkom work really I'm disappointed and confuse .I went so many times to their branch stores with no help they will tell to call the call centre .walmer park branch and Greenacres branch
