BT calling plan and sky

Just tried checking my calling plans on the BT web site but i cant reach the page,I get a message saying I have another provider on the line. Is this because of sky broadband on the line or has some company probably sky switched my calls over to them with out my knowledge? Ive phoned BT and they say another supplier is on the line but have no other information, they tell me BT togther option 2 is still active. can some of you peeps check on your accounts.

I get the same message.

oh must be the llu connection....hopefully

Yeh, Hopefully!! Our bill is due soon so will check itout after it arrives.
