AB Cement Tony Brown Horrible job installing a concrete slab Austin TX

Consumer beware! My 20 x 25 slab I got from AB Cement is cracking in several places after only 4 months.  The cost of the slab was not cheap.  I reached out to Tony Brown the owner for assistance but have not gotten any help.  The 3 guys working the job left a huge mess.  

There were cigarette butts, patches of wet cement in my grass and they left debris on the slab while settling.  Halfway through the job they ran out of cement and now there is a distinct line where one section dried before the next section was poured. 

They told me it would eventually seam together but of course, that never happened.  The crew didn’t even come with all the equipment needed for the job so they asked me to rent a $250 cement buggy to help them out.  They were not prepared for the job with equipment or supplies.  Do not use AB Cement unless you want to have to pay for a second job to be done.
