Can get better service from a snail in a fast food

I upgraded my 2mb adsl line to 10mb. I upgraded on the 28/05/15. The consultant was supposed to migrate my account to the new service. She however opened a whole new account. I had to cancel the old account on my own. Note: You got a fat chance if you think I'm going to pay double. The 10mb line worked flawlessly. For 3 days. Now my max speed is 2.1mbps. And is still so to date. Sad. Considering im being billed for 10mb. Upon manually cancelling my old 2mb account, the consultant did not advise me that I would be losing my email address. One that iv been using for several years. I have been trying to reinstate my old mail address for the past week, and somehow, it's no ones job. I get kicked from sales to tech to retention to adsl. And back again. I have spoken to 25 consultants to date. And still nothing. At one point i was told if i want my old address back i would have to pay a monthly fee. So i should pay monthly, because all your employees are ***********? I leave this comment here in the hope that my issue will be sorted out. And somehow, i still don't think it will. And please, if you're gonna give me a cut and paste response, rather not respond at all.
