Unhelpful and wrong info

The supervisors are unreasonable and unhelpful, there is no accommodation to the client and no attempt to accommodate, I cancelled a contract but my account is still being debited for that contract, there's no help with upgrades and in general just really irritated and disappointed with the service. What the people in the stores tell you is completely different to what the call centre and other departments say, there is a lack of knowledge on the policies and what is or isn't possible.
