Received a burr coffee grinder claimed to be for light commercial or domestic use. I bought for domestic use. Failed after less than a week. Ground one bag of coffee over one week and had to strip it down as per the cleaning manual and the drive mechanism was rock solid with grinds below the hopper outlet. Cleaned, tried to run the machine again and clogged up again. Cleaned and clogged again. Customer services refused to take it back unless I stripped it down and provided a photographic evidence of the fault. I said they need to sort it out. They then said I had no rights as I was a commercial customer and I was also expected to clean it regularly. Amazing, they think someone using it for light commercial use should strip a coffee machine down every 6 coffees taking 30 minutes each time, had I been using it for this purpose. She talked over me and was disrespectful and put the phone down 3 times. Had to contact credit card company to resolve.
