Poor customer service and work ethic

My account was disconnected for no reason, I then contacted the call centre to resolve the issue only to hear they dont understand why. Then I was further told I have been billed for PVR for the last two years of which I never requested or approved. 3 weeks later and there is no feedback only until I call and get rude consultants telling me they cannot help me further as the billing department is busy with the query. 3 weeks and they still looking at my account, I have asked to be refunded immediately but today I get an SMS to say my next debit order is due by the 26th. I am highly frustrated with this organization and I am further seeking legal assistance to resolve.
