Invalid HTML in DM to Virgin rep

Hi

Have had a regular DM exchange with Virgin (Ashleigh) for a week to transfer deceased father-in-law’s account to me. I tried to respond to latest DM but getting the “invalid HTML text, correct errors etc”. I keep accepting changes until a new message appears telling me I used my quota of messages for the day!

Can someone from Virgin urgently respond as need to DM to get the various issues sorted.

(This is the first time this message appeared)

Thanks
