Samsung S21 is nonsense phone.

Hi Samsung,

The cape town water front vodacom store tried to give me a new phone S21 plus ultra 'm not sure if the gave me the new one or the old one but the color was the same. The box was sealed as well. The phone new phone i collected last week has the same problem, it makes astatic sound like the previous one. This is exhausting for me now its been a month being inconvinced. I'm financial and emotionally exhausting. Last time I paid flights to take the phone back to cape Town, put petrol to collected it at the Grove mall, now I have to put another petrol to take it back to the Grove mall again after paying R19 500? I'm tired of this nonsense now. J would like to request for a refund
