Handbag Ruined from "Professional" Cleaning

I asked the Melrose Arch branch to clean a structured Michael Kors handbag in March 2020 - just prior to lockdown. On collection of the bag, it became evident that the cleaning had ruined the shape and left the leather wrinkled and the structure was completely squashed. They attempted to fix it, but the bag is still out of shape and has never been the same. I have emailed the company asking for help multiple times and received no reply. Terrible service. I do not recommend using this company for anything.
