Direct Pro Window Installed my window year ago and...

Direct Pro Window Installed my window year ago and it's leaking air during winter. we call them to fix since one year no one want to listen. their installer asked me that this leaking is minor you have to survive with it. I would suggest do not waste your time and Money with DIRECT PRO WINDOWS and door. Their managers and agents are great cheaters. only advise which benefit them.
After my first review the company Rey me that it was wrong choice of window by me but when their agent was arrive my place he pushed me to choose window because we are not window expert which one good or bad. Whatever their salesman Vladimir and Eugene advise we agree to select window. We do not know their sales team working to see only their commission not good choice towards customer. Their agent advise us and we agreed to install window upon their demonstration. After now one years Direct pro window GM called and excuse that our choice was wrong. How come your sales person not advise is for the right one. Even we told them we need window as the older one was there but they convinced us to showing benefit and make us choose bad one. I suggest please please do not go with DIRECT PRO. They all are one family and showing excuses after job done. If their mistake why they do not accept and fix the issues. Window is.long term investment and need to make right choice. I do not recommend anyone to go Direct pro until they fix my problem.
