DISSATISFIED MTN CUSTOMER

MTN IS GIVING ME SUCH BAD CUSTOMER SERVICE AND TREATMENT. AFTER THEY DELIVERED A WRONG PHONE IN NOVEMBER, THEY ARE JUST IGNORING MY EMAILS ASKING THEM TO CANCEL THE CONTRACT BUT CHARGING ME FOR THE PHONE. VERY DISSATISFIED WITH THIS KIND OF TREATMENT.I AM A 69 YEARS PENSIONER, I DO NOT DESERVE THIS TREATMENT.
