*****ing money from their client

My account was paid up by the end of January. It was paid in advance. By plus minus June, i receive a account that i own on my account. Nothing was purchased from December till June. I went into Mr Price home in Welkom to querry this. After hours it was determined that it was simcard airtime that was added to my account without my knowledge and without me receiving anny simcard. After numurous emails and calls this was not solved and this account accumulate R100/ month. Mr Price is fast to call to say you own them but when they ***** your money they do nothing about it. I have emailed Mr Price mobile, customer service and their ***** devision, no answer from them. I want this to be solved for me to close this account
