Lowes has the worst customer service than any other company I have worked with. Do not purchase Pella windows from them, the company is very unorganized and will not follow up with issues unless you make it your problem, even if you call them several times. When my new windows were installed the 3rd party company did a good job installing them. They noted that one of the windows was cracked and another one was short part of the locking system.. guess what this became my problem. No one from the installer or Lowes followed up ordering the replacements or missing parts. I have been in contact with Lowes several times and I feel like I am getting the run around. Just got off the phone with Lowes again and they are telling me the locking system will be coming the first part of June. Over a month after the windows have been installed. Also no date was offered for the replacement for the crack window. So beware Lowes is the most unorganized company to work with and seems that they really don't care when it comes to customer service
