Not worthy of one STAR .Appalling customer service . Constantly fobbed off with excuses .Requested to speak to a manager but none available all of them were in a meeting !!!!! I wish I had read the reviews first would not have touched them with a barge pole but as we had purchased these in a store in our home town we did not think we would not be able to resolve our issues with them We were told we had to resolve them with supply company AHF. avoid at all costs I am in my seventies and I have never dealt with a company like this before and don't ever want to again !!!!!!
