No customer care or consumer response - totally unacceptable !

I have experienced the most shocking customer service with Game online. I cannot get through to anyone on the phone - after holding for longer than 40 minutes or get any kind of response to emails that I am constantly sending. I am fully aware that we are all operating in very exceptional circumstances but to have no response in over a week is a more than frustrating. I ordered a Floormax Roto mop on Game online on the 13 of May, I received the parcel on the 18th of May. When I opened the parcel the mop was used, dirty and clearly not new. Since the 18th I have had not 1 response to my constant emails, have tried numerous calls to various numbers and not had any response. This is totally unacceptable. I have now requested that my bank dispute the charge and I will take my business elsewhere. At a time when online shopping has become quite a necessity you would think that there would be some kind of focus on customer care, this has left a very bad taste in my mouth and will definitely take my future business elsewhere!
