Worst accounts department in Africa

I really dont know when and where this will end up. I was with MWeb for 11 months when i suddenly on the 7 th of September 2019 saw that my router has no signal the same happend on the 8 th on the 9 th i decided to phone Mweb to find out what is wrong. I spoke to Kyle and he said Mweb had a contract with Cell C but terminated it. Therefore Mweb cannot continue with my contract but asked me if i wanted fibre. I said no as im in the process of buying a house elsewhere. Kyle then said i will be charged pro rata as i had used data from the 1 to the 7 th of September i was then told that i used 3. Something gigs of data from the 1 st of September and the charges will be R37.50. I asked him about the payment that was taken already by Mweb for September ge said i Can either have it reversed or Mweb will advance it to me back. I said to him i will reverse it back as it is for free at my bank. He also told me that it is Mwebs fault and therefore no penalty will be charged. And that the router will be uplifted as my contract with M web was 1 month early terminated. Or i needed to pay R423 for that 1 month that was left of my contract. I said they can come and uplift it. On the 10 th i phoned Mweb again and i was offered a package which included Telkom and not Cell C. My router was delivered on the 12-09-2019 and the old router was uplifted on the 13-09-2019. Today the 25-09-2019 i received a statement for a total of R1335.71 and that i am all of a sudden 30 days in arrears with an amount of R579. When i phoned today i spoke to Ryan who said he will escalade the problem and will sort it out. I then again phoned back and spoke to Another consultant whom now says that the router was never returned and that im being double charged a full premuim on the contract that was cancelled the pro rata data used for the 7 days and then a full amount of the new contract now it seems that there is no one who understands where they have gone wrong. I have a very good credit score this however will terminate that very soon. No one seems to have a higher authority cell or landline number. At Mweb. I told them that if the amount of R1335 will be deducted i will reverse the payment and they will bare the costs. As this is due to their incompetance of sending out a correct statement. Who can assist in this matter. Regarding my credit score and that im told that im in arrears of 30 days. I dont know what to do except to lodge a complain at the ombudsman. If anyone can assist i will appreciate it
