My experience recently not so brilliant: BA quickly agreed to a refund and amount before any of this kicked off in January. Great stuff!. Unfortunately the monies were never returned so I chased in in February. They said "refund would be with us soon". Early March they said refund would be with us soon and that there was no need to correspond further because cheque's in the post. Of course it is now impossible to get hold of BA in any way and because they have already agreed to pay it seems difficult to find another way to escalate this - most options would seem to be about getting the agreement, not chasing the debt. They have also not responded to Twitter. Any ideas?
