Vodaco. Premature Cancellation department is useless

Vodacom you have topped yourself once again. Firstly we wait for nearly 3 weeks to get a premature cancellation quote. After a lot of fighting we receive it and paid it. Then you do not cancel the contract and put the money as a credit on the account. We have emailed all the paperwork as per the email supp****. We phoned on Friday and was told we had to go into a store. Totally and utterly useless. Will you pay me out for my leave??
