Best Backflow Prevention Devices in Tulsa OK

I am very disappointed in Roto Rooter. I had a backup in our house. They scheduled some to come in an hour to an hour and a half. I had been checking the phone throughout that time. I missed the call by 4 minutes and the person that was scheduled to come to us was re-routed to another location. I am knee deep in cleaning up the mess. Why would you re-route the plumber if you missed a call by 4 minutes. Now we are unsure of when the next tech will be here. They can’t give us a time frame. Very very unsatisfied with my service. This is the last time I will use Roto Rooter. I should not have to stay near my phone every second. However, if that was communicated to me during the initial phone call, I would have not been cleaning up the mess and staying near my phone. Not good Roto Rooter, not good.
