Business ProfileforAbbott Industries Inc

The company sent 2 different plumbers for the job I requested. The first one ,there was no actual plumbing work done as there was a change on the work that needs to be done. The plumber spent 2 hrs talking in the hallway to his supervisor for which the company charged me 2 hours labor.The second plumber came to install a *** valve on the water supply line with the building maintenance staff assistance for water shutdown The process was from 9am-11:15am ,when the maintenance turned back the water supply.( I was charged $140 separately by the building for this process) .The plumber then removed the existing toilet and installed a new toilet which i supplied. The plumber finished installation about 12:30 pm then slowly gathered all his equipments in the bathroom. Around 1pm he said I am going downstairs "to get the papers for me to sign". I took him another 30 min to come up and only because i called since he was walking about in the parking lot then went inside his truck. All these I have observed from my window which is directly looking down at the parking lot. He came up and wrote 5 hrs of work . I told him its only 1:40 pm. I called his supervisor the following day and he stated he will look into it.. No one called me back, then about 2 weeks later they emailed me a bill for $1,612.18 . They charged me 7 hours of labor ($146.25/h and $506.50 for the *** which a supplier quoted me for $189.00 I don't mind paying the hourly rate if there is actual work done but i have a problem when contractors prolong the work unjustifiably. On top of this, they are charging me $1612.18 and the job is not completely done yet.there is still work to be done.
