Samsung sells **** products

I purchased Samsung S22 Ultra on the 26 of April 2022 and I have noticed that there is a problem with network, I took it to Samsung in Canal Walk and they said is Network service provider, I told them that I have Huawei cellphones and the same network is always working, they insist is not their problem, I went to Telkom and they said there is enough network signals in my area, I took it back to Samsung store again and I was referred to Samsung Technicians at 78 On Edward street, Tygervelly, and they told me is not their problem, but if I want they`ll book my cellphone for 3 working days for wipe and restore new software. 3 days without a phone. with no guarantee that the phone will be good, I rated Samsung products very high. But this time I am disappointed. Especially the expensive cellphone like S22 ultra
