Terrible service, rude consultant!

Telkom is terrible. We logged a call on 17/02/2020 to move our line to a new address. I phoned yesterday to follow up, the lady assisting me told me that there was a problem with the address so we fixed it and she told me to phone back today to find out if the address is correct. So today I phoned again, the lady assisting me was very rude, told me to not phone every day and that I'll know when everything is sorted out. If our line doesn't get moved this weekend like asked last week we will cancel our contract because I dont know why we should pay for terrible service!
