Flooding, Sewer & Water Leak Issues

Me yet again... After the last visit, all was really clear for most all day & evening, but seemed like it's built up again. I had a plumber come out to video my line to the trap, and all is clear there. I believe that there must still be some thing blocking the flow after the vent. The technician you sent ( Fred?) seemed to think that there had been some obstruction, and we thought he got it on the 2nd try today, Would you mind one more try at clearing it. thank you
