Disgusting service and poor quality device.

I upgraded my contract on 15 May 2021 and choose the Samsung A32 handset on recommendation from the consultant who assisted me at MTN Waterstone Village. I only started using the phone on 21 May 2021. On 26 May 2021 the phone could not be switched on. The phone was then taken back to the store where the consultant tried switching it on and after a while the phone switched on. The consultant informed us that "This is normal for Samsung phones and that the phone will do this at least twice in its lifetime" I was then advised to take the phone like this as there was nothing they could do. I also showed them an ink mark that appeared on the screen and was told this is also normal. I find it totally unacceptable since I have had samsung devices before and this was not normal. I also feel that the consultant was not helpful at all. I have been a MTN client for a while and a loyal client as well. If this how MTN staff rewards loyalty, I most definitely want to terminate my business relationship with MTN.
