Incompatant staff

Accompanying my father to the store for him to do a sim swap we were informed the sim was registered in someone else's name. Advised my Busi to get affidavit witch we did to then be told after waiting another 45 min in que that it could only be done tomorrow morning because she didn't know what she was doing and frankly seemed not to know how to use system. Following day she only then claims to lodge complaint on system and says it will be sorted by the end of the day and she would call before closing. Later after no call I went back to now be told it will take 72hrs? Then was rudely told that if I can't wait 72hra I must bring a copy of the person who registered sim? Person I have never met because card has been used by my father for last 5 years from new so it's a fault on Telkom's side that I'm now big told to solve? Think it's time to wash our hands of Telkom as the only thing their staff seems to know how to do is ask for cooldrinks
