Titan LLC Anchorages Landcape Contractor

I was quoted a cost of approximately $2900 for the job.  I had a $2500 credit with this company.  What I wanted was approximately a 2' high border around the garden. The garden outline was there previously.  What I got was an outline of the garden with rocks.  They were only going to put one layer of rocks and I explained this wasn't what I wanted.  So, they put another layer of rock on top so what I got was a 6" high border around the garden.  I paid almost $500 out of my pocket, which I shouldn't have done but I did because I thought "maybe it's my fault there was miscommunication?"  I contacted the contractor asking for them to deliver more soil since they only brought enough soil for a 3" border.  I was told he would come over and deliver the soil.  After a few months of this and getting frustrated I contacted the General Manager.  He said he would come by and take a look at the job. I contacted him via email, as he requested, when I was back in Anchorage, and I didn't hear back from him and after a few days I left a voice message on their answering machine.  When I still didn't hear back after a few days, I sent another email and the General Manger responded he was available the next day.  And the next day I didn't hear from him at all.  I sent an email back to the General Manager stating that if he had no intention of coming to look at the job, he should have had the courtesy to tell me. He replied asking me why I had taken so long to contact them and I explained I was given the runaround by the person who completed the job and also by him, the General Manager.  I feel that once a job has been done and payment has been made, it is not a benefit for them to do anything else for the customer.  Where is their integrity?
