No response from supplier

On the 26th May 2015 We phoned and asked Multichoice to cancel our subscription as we were relocating and would get back to them when we were settled. On the 1st June we checked and we had no reception, however the D/Order went off our bank account on the 01/06/2015. Now when we want to reconnect they say our account is in arrears. We have been trying since last Thursday (30/07/2015) to get reconnected. We visited the Multichoice offices in Devereau Ave. Vincent, East London twice now and they say they cannot help us we must use the call centre. Norma from the call centre asked for proof of the June payment which we emailed to her. but I have had no further response to my emails to her. <br> <br> What must I do to get some service, I have been a loyal customer for 17 years and now am being treated like this. How long do we wait for a response to our Query
