contract agreement

<p>I renew my contract and agreed on a certain amount for payment of R299 for the month...ever since upgrading I've been paying almost close to a R1000...I come to the store and all they say is that I need to contact the call centre...with all do respect I do appreciate the service they provide but as a client I can't afford this premium...sometimes I leave it and phone in several times just not to mess up my credit record...just to get an sms afterwards that your case has been closed...no feedback provided ...</p> <p>Please assist </p> <p>Contract no. ********** 806</p> <p> </p>
