Everything! Communication system is very poor. They don't keep to promises made. Staff don't appear to know how to deal with issues - promise to do so but don't keep promise,. Don't return phone calls and difficult to get through anyway. Recorded advert on "call waiting" assures customer Peter Vardy is more interested in a satisfied customer than in making a sale - this phrase is totally inaccurate as it is obvious customer satisfaction is bottom of the list of priorities - they take customer cash then ignore issues arising. Advising my friends to avoid Peter Vardy and sorry I ever visited
