TOBi chat closed by support whilst replying, now greyed out and won't open a new chat

[Bulmer]

In the midst of discussing options with my partner about how we wanted to approach the end of our 24-month contract the chat was closed by the support member of staff and I can now not re-open a TOBi chat and start again.

Is there a cooldown on this or have I for some reason been blocked? I was not abusive or bad mannered.

Thanks in advance for any help.

EDIT: Update approx 2 hours later and it's still greyed out.

Hi @Bulmer 

If clearing cache and cookies and or using another browser or device does not work I'd suggest to try Live Chat or call 191 for assistance. 

I wish you all the best.

By this morning it had sorted itself out.

Thanks for your help nonetheless.
