I have just received my . of a Samsung S21. I was very disappointed to find out that it did not come with a charger and had to purchase one separately at my own cost. I feel that selling a phone without a charger is selling something which is not fit...

I cannot hear anyone on the other end of the phone unless I put them on speaker. I have tried adjusting the in call volume but that doesn't make any differance. Can anyone help please. The phone is less than 5 months old?
