Substandard Workmanship Warranty not Honoured

During March 2014 Silver Solutions was contracted to completely refurbish my house roof. This work entailed lifting roof tiles, replacing damaged or rotten timber, replacing the plastic waterproofing material under the roof tiles, etc. The work carried a 2 year warranty, with the owner swearing on his spouses life, that he guarantees his work. He was paid in full for his services. Almost immediately we experienced roof leaks, ceiling damage etc. The company owner was contacted, over and over, to date ignored our please and requests for assistance. Promises of visits to inspect the damages are not kept. Our home insurance Bank refused to pay for recent storm damage, as they claim there is no evidence of maintenance having been done, regardless of the substantiating documentation.
