How dissatisfied I am with NAME_1's service is not in the dictionary! I simply can't contact anyone (besides a robot that doesn't solve ANYTHING) and I can't even access the application (which all the time gives some error). I just wanted to change the date of a technical visit appointment that they scheduled on a day that I DID NOT choose and clearly said that I would not be at home and could not receive them. They sent me an email saying that changing the visit data was only via the NAME_2 (which simply doesn't work!!! I can't log in because it gives me an error all the time). When it comes to selling the service, they are super helpful, when it comes to collecting the invoice, they are a pain in the ass, but when it comes to providing easy and more accessible channels to resolve issues, they don't! What the main feeling of customer for the text before (in 1 word)
