Forget AFHCO

I have contacted AFHCO on Tuesday (17/03/2020) and was assured that I would get a contact from a letting agent within 24 hours. I have contacted them twice on the following day (18/03/2020) and was reassured of the 24 hours deadline. On my second call I was told the matter would be escalated. 48 hours later I DID NOT get any contact!
