No show cabinets

We paid this company their required 75% deposit June 11th without hesitation. Month 4 without any work done or communication, we decided to get our legal representatives involved. He (the owner Gerard Jenniker), then made promises and sent his team to lay down the carcasses (off cuts from previous jobs - installed with extremely poor workmanship) to shut us up. Month 5 will be next Monday and Gerard has now opted to ignore messages and calls.
