Hi Swansdm
Thank you so much for your reply - it re-assured me!
Yes - QQQ and others are out - I found out about because I got a (false) margin call - scared the hell out of me as I have had issues before with IG.
Perhaps worse was that I couldn't get through to customer services even though they were supposed to be open from 08:00 Saturday - as a result I decided to add funds to my account (which I didn't really want to do).
Pleased to see it was sorted for me now by contacting the new number 0800 409 6789 (make a note of it for future issues)
Thanks again!
