Urban Company — Painting Services

I have taken Painting Services for my client on 15th November, 2022 and the same was completed however the painter who visited the site has agreed completing work in the scheduled services however he added another service without informing me. Though he told we need to add separate service and when i explained the scope of job that he needs to perform and the work i have added to do he found justifyable and said ok sir i will do it. And later to my surpirse he says it should be added as another service which means he is cheating for extra money. And when complained the same to Urban Company i had to talk to Ms. Purnima Kumari ([protected]) she says its ok sir you pay the amount. I dont understand what does that mean by saying its ok. Also she says painter is very good and he will do good work...she is simply backing that fellow but not able to understand the issue of cheating customer by accepting to perform job in assigned task and later adding another task for his benefit.
Please do take stern action against the both painter and Ms. Purnima Kumari.
