Shocking Customer Service.

I completed an online request +-8 weeks ago to have my ADSL line moved to our new address... 4 weeks ago I phoned to enquire on the progress, just to be told my request is not on their system. Then I logged another request and waited. Beginning of last week I phoned again... Just to be told that their is no request on their system... So I logged a request for the 3rd time, making sure they give me a reference no ********** . Since Monday I have left 2-3 messages per day with the 10213 switchboard for someone to call me back so I can get an update... I am still waiting!!! And was rudely told 5 minutes ago that their is no supervisor who I could speak to, neither do they have another number I can phone!!! I am at my wits end... I am sure that I won't get discounted my monthly premiums, even though I have not had a line...

Can anyone help? Please
