Telkom billing issues

Hi, so I have had my fixed residential ADSL line from Telkom installed 2 years ago and was happy with the services then I received a call from a Call Centre offering me an upgrade to a faster LTE line. The contract was done telephonically and the Telkom LTE router and SIM was delivered. I was informed thst the SIM was activated and that I should wait 24-48 hours fir the activation request to go through. So 3 days later I swithed the router on at around 4PM and it worked like a charm, upload/download speeds were better than those of my fixed ADSL line's......However, at 5PM sharp I could not use the Wifi anymore, I logged into the Telkom App and guess what???? Telkom "upgraded" my residential ADSL to a Business hours LTE contract which was absolutely useless to me seeing that I only use my Telkom out of business hours whdn I am actually at home. So on around day 5 or 6 I arranged for Telkom to send their courier back to fetch the useless piece of junk, the courier company fetched it on around day 7 or 8. Then I noticed a strange debit on my bank account from Telkom....I phoned my bank and reveresed the debit order, phoned Telkom and logged s query with their accounts department and was assured that the query would be resolved. Yesterday another Telkom debit order was send to my bank, this time for 3+ months' payment for the Telkom LTE services.

Telkom needs to get their act together and resolve my billing issues ASAP.

I think I should just go ahead and cancel all my Telkom contracts with immediate affect.
