VODACOM 4U CAPE GATE DISGUSTING AFTER SALES SERVICE

I upgraded my contract for a Lenovo laptop - this was done on the 6th Nov 2022. When we set the laptop up we realised it was abnormally slow, on Tuesday Morning 8th Nov i returned the laptop and the sales consultant checked it out and agreed it was abnormally slow. Please note that i returned the laptop within 2 days. it is now the 23rd Dec and i still have had no feedback from CJ the manager or anyone in the store as to what is happening. There was a backwards and forwards that i must sort it out with Platinum and then Packserv which i refused to do, The laptop is still at the store Vodacom 4U Cape Gate. Please can someone get back to me, I have no doubt i will be charged for my upgraded contract which i will not be paying.
