TNA Concrete

We hired TNA Concrete (Tony) to do the above mentioned work in the fall of last year. They even had an A rating with the BBB and of course said the right things. Without telling us they then sub-contracted the work, claiming the people that showed up were working for them. Needless to say, the work was of extremely poor quality, less than a year later, there is cracks in multiple spots., they never placed a footing for the retaining wall extension, poured concrete into cracks in the retaining wall but never removed any of the cracked loose concrete... They never returned any calls or e-mails about our concerns, stating that Tony had gone "hunting". We had retained a portion of the cost to be paid on completion of the job, yet severail months later they sent us a bill for the Rest of the bill. I again tried to contact them, to no avail. I sent them and e-mail stating I'D pay the bill when they returned to complete the work in a satisfactory manner, and haven't heard from them since. Extremely unprofessional and poor quality work, and misrepresentation by the company and Tony himself.
