How to lose a customer

So guys. You decided to repair the lawn mower that I purchased and that died a half hour into first use. Ref ***. Purchase and return consumed four hours of my life Now you have repaired same, and want me to waste another 2 hours to pick it up. This amounts to around R6000 of my reduced consulting fees. No. I am invoking CPA 56(2)(b). Your refund is now due. Maybe a course in customer retention is overdue? We mow on.
