My garage doors was automated by Stack Garage doors. I am extremely happy about the product, but unfortunately the Stack Garage Doors did not keep to their quote and did not install the battery back-up system. This was quoted and paid for. THe day after installation I reported the omission to Stack doors and eversince I am not getting feedback or a phonecall to advise when this will be installed. I am very disappointed as there is a 3 year guarantee on the product and this kind of service does not tie up to a relationship that must be benefitial to both parties for 3 years.
