Disgusting after sales client services

I bought a Mecer Guru laptop online. It was delivered on % September 2022. I phoned vodacom on 12 September 2022 and again on 16 September 2022 to report that I was not satisfied with the product as I had endless problems with the internet speed, the storage space was less than my cellphone and general product does not meet my requirements. I was told that someone will phone me back. Nobody phoned. On 29 September 2022 after about the fourth call and no satisfaction I was informed to take it to the vodacom store in Tygervalley, at the store they wanted R650 to take the laptop which I declined to pay as the laptop was still in its return period when I first called vodacom on 12 September 2022. The store manager at Tygervalley phoned vodacom who informed him that Vodacom will send a courier to collect the phone at my home. Having no courier collect the laptop and no response from vodacom I phoned again on 3 October 2022. On this occasion like the others the matter was to be escalated and I would receive a call. I waited for the call as I was now very disgusted and angry. I then emailed vodacom online and up to today NOTHING was done. I have been with Vodacom for more than 25 years and have heard complaints from many and now realize that customers are taken for granted and not taken seriously. I am sitting with a useless laptop in a box for which I am paying. I was prepared to exchange it for a better product. This is the worst customer experience I ever had in my 60 years. I have spoken to many of their client services agents and have been passed on to many and nobody has done anything.
