Sub par internet service for 2 months.

Since the 25th of April I have had a terrible internet connection. Paying for a 4-10Mb line and receiving a 512kb line instead. As far as I'm aware this is a breach of the Consumer Protection Act.<br> <br> During these past 2 months I have been given multiple promises that a technician would tend to the problem and yet, here I sit with an internet connection that can barely load the web page to make this complaint.<br> <br> I then ask to speak to a team leader at the call centre and I am told that a team leader or manager will not be able to do more than what a call centre agent has already done for me. Which I refuse to believe and take to be a lie.<br> <br> So within the last 2 months I have had minimal to no internet, been promised a technician will contact me, and I did not see one. I don't see why I should pay for something I'm not receiving. This is my last hope to get something sorted before I decide to take my business elsewhere.
