Empty promises

I have been asking for help with premature cancellations on four numbers. After a long battle and lots of struggle i received the quotations. I sent of the signed quotations and all docs requested with proof of payment. They said as soon as payment is made and reflects it would be cancelled. Firstly they took it has a payment on my account balance and later it was rectified. I sent emails every second day with only reference numbers and then the calls are closed with no one phoning or emailing me to say what is the progress. I am so tired of asking and asking and nothing happens.... When these numbers are cancelled eventually I will never renew my contract again
