9 months to get an answer

Our contract was increased Apr 2014 from R196 to R406 with no communication or agreement from our side. My husband has been querying this since July 2014 with emails as well as contacting the call centre, receiving no clear answer. My first caal to call centre was 23 Jan 2015. Every consultant gave a different explanation, promised to get proper info and come back to me. They never did, they just close the call. I also asked the contract to be changed to a local one which they also did not do. They refuse to do any refunds or tolet me speak to a manager. Today I have reached my limits after they once again did not phone me back as promised, I asked the lady to please cancel our contract with immediate effect. This cant be done without my husband as main member giving the instruction, and yes, sorry for you mam but we require a 30 day notice period!!! BUT they can double the fees without ANY authorization with immediate effect!!??
