Incredibly disappointed with speed

[qusvz]

I previously posted about a man at the door advertising that fibre 50 was my available top speed! Yet it was not, i then contemplated upgrading to fibre 67. Now it doesn’t show up on my deals. 
why can’t I go from fibre 50 to fibre 67. The speed is extremely poor and everything cuts out from tv to YouTube. It is terrible. My experience so far has been horrible and now I’m locked into this silly contract. It seems that the speed has become extremely bad after the testing phase closed. Sky was much better, it was smooth. I’m happy to pay extra for the upgrade but getting the to load is a nightmare even when using my mobile data. I ask for someone at EE to help me upgrade. As I’m stuck with you for 2 years the least you could do is help me out a bit and try to better my experience a tad.

You are probably exceeding their guaranteed speed & so would have no comeback.

As the actual speed is so much lower than would be expected you could try rebooting the router & posting the router stats again (point 1.)
