Good Deal Stone & Cabinets

81 year old senior woman on a small pension without sink or dishwasher for 3 months as she tries to get Good Deal Stone & Cabinets to replace the counter tops that they installed that are too small. The result is there are 3/4" gaps between the counter top and cabinets, the slide in stove is 3/4" lower than the counter tops as the countertops were installed using 3/4" plywood that raised them up too high. There is no overhang. The company is claiming that the countertops are a standard size (even though the job is custom). The contract was for 25.5" wide and the counter tops are in fact 24.75" wide. Many unanswered phone calls.
