Mr PriceMobile big no no

This business dont deserve even a 1 star. I have posted a review on them awhile ago. The next day the phoned me and the contract was cancelled, but now everyday I get phonecalls about outstanding fees. I mailed them the cancellation proof and still they phoned me. Wednesday they deducted R199 from my bankaccount AGAIN. After everything was cancelled. They dont return my mails at all. I need this moñey to be paid back asap!!!!!
