Vodacom upgrade nightmare

Took an upgrade on 26 April 2023 which included a Mecer Wizard Laptop. It arrived 12 May and as it was a gift it was only opened 16 May. The laptop only showed a white screen. Went to 3 different Vodacom stores and the third finally looked at the laptop as the other two indicated that telephonic upgrades are not handled in store. The 3rd shop noted that the laptop does not work and gave me a Vodacom number I should contact. Since then I have phoned numerous times and I get the same story...the back office will phone me and arrange for collection. It is now 19 June 2023 and still I have the broken laptop in my possession and am paying for the contract. I would highly recommend NOT to EVER upgrade online or over the phone as this department of VODACOM is definitely a step backward than the Vodacom stores in terms of service.
