Can't do sim swop

I went to Telkom Somerset mall on Thursday 22 Oct for an upgrade, the lady said i must come back on Sunday for the sim swop. Sunday morning early i went in got my phone and signed for it but they could not do a sim swop...he said i must come back later, went bsck at 1 and they could not hrlp me and said i must come back at 4...i went back at 4 and they still could not help me, the guy said he will phone me on monday but it will take 24 hrs. Monday came... no phone call so i went in again. They still could not help me something about an back log and system error... sorry mam it will take 24 hours i promise i will phone you... so 48 hours is over...still no call from no one..... it is PATHETIC!!! And i cant call them either... i phoned support and they also could not hrlp just said they are sending an email!!! I feel like cancelling everything!!!! It is now the 27th and i still cannot use my new phone... heaven forbid if they charge me for these day that i wasnt able to use my phone.... i refuse to go back again cause i already almost wasted half a tenk of petrol and everytime i get told that i must wait 24 hours.... Seriously GET IT SORTED OUT!!!!!
