Forced to use this company since I was living in a rental home. The house had a back up problem, the tech says it was from using wet wipes. I told him we don't use wet wipes. Whatever, problem was fixed. Temporarily. Started backing up a week later. Same tech comes out, not as friendly as the first time. Says it's from wipes again. I say, again, I don't use wet wipes. He says the mess is not his problem and it's our responsibility. Ok fine. Then I get an email from my rental company. They tell me I'm responsible for the bill due to negligence since I continued using wipes. It's not the bill I'm frustrated over. It's the fact he called me a liar. I think he just did a terrible job first time out. Oh well, no way to prove it.
