i give one star because there is no option to give any lower. Worst experience ever.
They were picked by warranty company. i can confidently say they came just to deny the claim and sell their services. i don't remember name of guy correctly but i think it was Robert.
He Spent 5 minutes in my house. Did not have patience to listen to any of my concern. he came prepared with one line " it's not covered" if you want it fixed we will charge 400$. i asked him to show me proof that it's not covered he said if i want proof then it will require another 400$.
He completed his evaluation in just 1 minute and spent rest few minutes on selling the fix and writing an invoice.
If ever, your warranty company picks them please ask them to send different company. this company technician was very rude.
