I bought my sanitary wares, kitchen hobs, hood, mixers and accessories from them and was served by Penny. I must really give credit to her for her patience as I am not an easy customer. She took time to explain everything I asked. Anyway I had no problems with them at all. My ID liaise with them regarding delivery and installation and he commented that they were very helpful in providing information and service. In fact he recommended quite a few of his clients there too. I sincerely hope they can solve your problem. Perhaps you wish to elaborate the problem of your mixer?
