Huawei Y62 phone

I bought 2 phones (huawei y62) 2 days back, I used mine last night but only to find that the volume of the phone was way too low, checked the settings and all, took the phone back to Mr price Rustenburg Waterfall mall, the lady who assisted me checked it , she did factory reset on the phone and the volume became OK,she told me they can't exchange the phone, I'm having a phone that got factory reset as brand new as it is, and got told "we never had a problem with huawei, what did you press", If Mr Price won't exchange may I please have my refund, I'll buy a new phone elsewhere.Im not happy with this phone and my 7 days is almost ending, I don't want a factory reset phone right
