2 weeks - NO RESPONSE

Bag went missing for days. When it was delivered it was badly damaged - beyond repair. Delivery gentleman said it had been noted. Gave us name of OBERT to call. He doesn't answer phone, messages or mails. It is now 2 weeks later and I have begged, pleaded, shouted, repeated written mails, repeatedly called. NO RESPONSE. BID AIR reckon they are only service provider. Simple matter becoming huge issue.
