Roto-Rooter Plumbing & Drain Service

I placed a service call to unclog the bathroom pipe. First technician named Max came in and informed me that the pipe is clogged and he needs to open the toilet to fix it. After trying to open the toilet for 30 minutes he informed me that he does not have the right tools and skills to open the toilet and a more experienced technician will come to fix it. 2nd technician named John came and informed me there was no need to open the toilet and Max should have fixed it through the tub drain. I asked for lower fee as now the work is less and no need for toilet disassembly but he said that I have already signed the paperwork and no I have to pay for $550 just to put a rod in the pipe. I agreed as I did not have a choice and I needed the bathroom to be fixed. John informed me that everything is good and I paid the service fee. Next day I noticed the water drips from the roof. John again came in and cut the rood in couple of places and informed me that the toilet is leaking. John said that he needs his manager approval to perform the repair free of charge and I need to call them on Monday. On Monday I called again and explained the situation and I was told that the work is covered under the previous contract and the technician should not charge any money. Technician came after 2 hours and started asking for $520 to fix the leak. After several calls to the customer support and the corporate, they refused to fix the leakage unless I pay $450. This is simple fraud. You come to somebody house, cause a leakage, and refuse to repair it. I am left with water damage, roof damage, and now I am working another company to fix the leakage that was cause by unskilled technician. Worst company to work with. Don't recommend anybody to use it.
