No further response to my previous complaint

I complained about shocking service Sunday 21st June. I received two responses on Monday 22nd that the matter is under investigation and I was quite impressed with the change in attitude. Unfortunately it is now Friday 26th June and it seems as if the same attitude is prevailing that forced this situation on in the first place. May I also point out that House and Homes previous response stated that they were investigating their insurance department, whilst my complaint is cleary aimed at the bad attitudes of their reginal managment, who have continued to ignore this matter to date.
