Problems since upgrading

On 8 February 2016 I was contacted and informed that I qualify for the 8Mbps line, which I was happy to take and upgraded. Since then I never could reach that speed but only half that speed. Contacted Mweb and was told that it would be referred to Telkom. Then on 12 Feb my Internet goes completely dead. Phoned again and the problem is with Telkom. I follow up every 2nd day, but the problem does not get resolved. On the 20th Telkom comes out and fixes the problem, but still not the speed I'm paying for. Telkom does a follow call on the 22nd and am informed my line does not qualify for a 8Mbps as I'm to far from the exchange. Phone Mweb, they downgrade me back to my original line speed, but I must still pay a portion additional as the debit orders have already gone through, that I can take as a credit will be provided. 2 Hours later my Internet goes down again. I have spent 150 min on my phone to Mweb, and the response to the new outrage - will log a line fault with Telkom. All I want is my Internet back on again. I hope someone can help me.
