Lifetime roofing llc

I had Lifetime Roofing replace my asphalt shingle roof in early of October of 2020. Along with the roof I also wanted the gutters repaired that were leaking at the joints. In late October I had water leaking into the house between the main section of the house and the addition as well as water leaking through the joints in the gutters that they were to repair. I called and he came out in early November of 2020 and added some caulking along the flashing between the main house and the addition and took a look at the gutters. During the winter months I did not notice any more leaks between the main house and the addition but I did have some ice icicles along the gutters. In Mid-March of 2021 it started to leak again between the main house and the addition. I texted him that the roof was leaking again, and he responded that he would stop by the following week. He never showed up the following week. I have since tried several times to contact him by calling and texting with no response.
