Talktalk Speeds

[john4647]

I recently changed from BT (Yahoo) broadband to Talktalk. Since then, some but not all web pages are very slow to load, particularly e-bay and Paypal. Also my internet banking website takes 8-10 minutes to load. I tried the speedtest on this site and it recorded 0.56, 72, 573. but I don't know how fast it should be. I have spent hours talking to Talktalk's helpline and they don't seem to able to help
Any suggestions welcome.
(I just tried the spell check on this site and cancelled it after waiting 5 mins for it to load)
