Contract cancellation reimbur*****t

I took a contract phone through telesales, when the phone arrived i was not happy and returned/cancelled the contrat within the 7 days period however an amount of R199 was deducted from my account for 8 months subsequent to my termination of contract. I then phoned in through vodacom consultants to check the status of my claim and i was told to wait for for 21 working days, when i phoned in again after that period i was then told to wait for another 3 working days, this claim is over a year now and there is absolutely no one to resort to as i am always told that my claim is with credit department. All consultants that i liased with promised to keep me updated about the claim, no one did till date. i am very dissapointed at this service provider.
