Requested repair for my solar panel/powerbox

In May 2008, just as I was clearing out my condo in St. Catharines Ontario for the new owner, I purchased a solar panel and a power box - the boxes showed these were the right units for each other - so I could have free energy to power my laptop, cell phone, radio, and fridge inside my van as I traveled about looking for a soft place to land. The $590 cost of these two items: $590. I have been able to use the power box but it recharges from electric energy, which doesn't save money. If I can use solar power on a daily basis, I can shave some money off my electric bill.

Only after I left Canada did I discover that the plug on the solar panel didn't fit in the Powerbox. So now I'm sending a detailed letter, a copy of the bill, the end of the plug and a request for a replacement that fits. I don't want to have to drive to Ontario if I can help it. I'm hoping the Canadian Tire store employee will be able to remedy this easily and it won't get stuck in Customs in either direction.
