This is the first time I have used this company and I must say i was quite impressed with the service. They two servicemen came along were polite friendly and did a good job. However I felt pressured into taking out a service contract I didn't want and when I said no, the salesman persuaded me to buy filters at an extortionate price, which I only discovered after they had left and I googled the same filters from amazone for a fraction of the price. Very disappointed not sure if i will use them again. I did complain to the office but they gave than usual response of our filters are better quality.
