Incorrect cancellation fee

I have been incorrectly charged a cancellation fee for my cell phone contract of +-R12 000 by Telkom Mobile, and neither the store where the contract was taken, nor the call centres have assisted me with resolving the query. <br> I am continually told it has been reported and will be looked in to while my account was charged and due to non payment I have been charged bank fees. <br> The store manager is never available, neither during the week or weekends and the store never answers their phone.<br> I have had enough and as a last resort to get this resolved, I am posting this. <br> My case number is : ***2<br> <br> Thank you<br> Regards
