My Unfortunate Issues with Z1Motorsports.

I suggest that you escalate the issue and speak to a supervisor, manager, VP, etc. Let them know you and your friends on this forum are long time Z1 customers.
In no way should any reputable company, let alone Z1, leave you 'out to hang' in this manner. I do believe you probably spoke to a junior pencil pusher who was just quoting the standard company policy on customer service/complaints. He cannot make the final decision based on one call. You need a resolution and one that will be acceptable by both parties.
Remember to be nice but be firm with your demands.
