Lack of communication and no items delivered

The school which my son attends school at, has used this company to manufacture/design their grade 12 Jackets. I have paid in February his jacket. Winter is about to end, preliminary exams are upon them and no jackets. This in my opinion, as a parent who has paid for a jacket, contacted this company and had no feedback on the last messages sent is totally unacceptable. I hope this will send a clear message that I am frustrated and totally displeased with their service or lack there of.
