I am sorry to say that this Company (who I hadn't used before),let me down at every level. On two consecutive days in in mid February they cancelled appointments because of a problem with their van and I wasted all that time waiting for them. Then finally the engineer came on the third day and spent 10 minutes diagnosing a new part. A few days later they said the part would be £369. For this service I paid £125 up front. When I complained, their attitude was 'terms and conditions'. I asked about a complaints process and they hadn't got one (or at least not one they would tell me about). I shan't use them again.
