she is the one who purchased it for me

She brought an mtn tablet gave her the money to purchase because I trusted her as one of the employee of a one of the leading network , got the tablet on the 30 march 2015 , then started to freeze on the 21 of april 2015 , didn't even mark 30days after purchase, I was even getting strange calls frm anonymous , which clarified me tat sum 1 using it !4 me , how can 1 do repairs on a product which is aint older than 6 months?? , is a possibility of getting a re-fund coz I don't think I will settle for placement because I'm not satisfied wit the MTN STEPPA TABLET anymore #yours regards THOKOZILE MTHETHWA .
