Hi Scott.
First of all, please don't swear. This is a family forum and as the rules state we don't tolerate swearing. Thanks
Now i'm with BT and yes I have the same problem. From around 4pm - midnight the speeds are terrible. BT have told me we're being capped due to being classed as a heavy user (Downloads quite a large amount). Now apparantly only 1% of users are classed as this, which I find pathetic and don't believe that one bit.
When we signed up we were not notified of this and no one said we could be classed as a heavy user. I've been thinking for some time that we could claim it as a breach of contract and possibly get our contract terminated. I've not tried it yet, but you could start with that.
How long have you got left with the contract? I know there's a phone number to ring and you can ask, but I can't find the number anywhere!
If it's just a few months left on the contract i'd put up with it to be honest. Save you the hassle of paying for phone calls and maybe a fee to cancel the contract.
