Pella review: Door installation

We purchased a door and it was finally installed in December 2020. The peephole was missing and we contacted the agent, who told us it would be rectified. It's been 3 months of sending messages, promises of resolution, and no follow-up. We spent quite a bit on this door, it's only right that we get what's we paid for and that Pella upholds what's in the contract. Very disappointed.
