Mega Interlocking & Custom Designes - No longer in business

On May8,2013 I intered into a contract with Mega Interlocking for $3,350 to get my interlock done.At June8,2013 their crew started fulfill a project.But until now ,today is September 6,2013 they did not put Polymeric sand into the joints as supposed to be done by contract.Nothing has been changed after repeated calls to the customer service and phone conversations with project manager and with owner David. Three month of excuses and promising they will be there one day convinces me that I made a big mistake in choosing this company.So be warned when dealing with Mega Interlocking.
