Bad service, no integrity

Took out a contract with above company to promote my business. Never came to the party by doing any work as promised. Did not deliver their service on time, but demanded payment. Paid 3 installments, and still nothing, Told them we wished to cancel contract, but they just ignored the problem. After numerous correspondence from myself and my lawyers, I am now blacklisted with ITC as bad payers. DO NOT HAVE ANY DEALING WITH INTERFACE MEDIA.
