Dobbos Home improvements

We paid in full as requested by Dobbos and was told the work would be completed in 2 days. It has been nearly 2 months and after Dobbos half removed the front section has not been back. After several calls he said he would finish it by the end of the week. Nothing happened. No show. He will not return my calls and my property looks terrible with a huge mess out on the front yard. The 8 tiles laid in the back yard lifted within 2 days of laying and are all uneven as they have just been laid on top of the dirt. I would love to have the job finished or money back however i cannot contact him.
