Confusion over TSC 2 Year Warranty 15/5/2014

Just over a year ago, a potential customer requested a quotation on three TSC printers. After negotiating for a week they decided to opt for a cheaper (R35.00) alternative brand printer from an opposition company.

The potential customer brought in two of the xyz brand printers, and insists that we should repair them under the TSC 2 Year warranty. The logic behind this is that the 1 tear warranty on the XYZ brand has expired, so we can repair these based on TSC's 2 year warranty.

I wonder if the fact that they did not even buy these printers from us has ever crossed his mind.
