BAD BUSINESS

I have been struggeling for the past 2 years now to get ahold of Mr Price Mobile. A few years ago they provided me with a "special customer deal" that was for a tablet for only R150 p/m.. that contact was suppose to end last year 2016. I tried to email and phone them to assist me to cancel the contact but the number on their website does not exist and they dont respond to any of my emails..they have been deducting random amounts via debit order. I have tried stopping this with my bank and they do say that they have stoped this..but yet it still keeps decuting. I am so frustrated and dont know what to do! Please AVOID doing business with them
