Client:
Hi! I'm not comfortable paying anymore while my amp has not been fixed. I respect you as a professional and am hoping we can resolve the issue. I was expecting an estimate when I dropped it off with you. I am happy to leave it with you again until it is paid off and in working order. I'm not going to pay for any additional repairs but I'd be happy to continue paying off the initial bill once it is fixed.
Me:
This is an unusual case. I do not offer payment plans, and I should not have let you leave with your amp. But, here we are. I warrant my work for 30 days. But you didn't mention any trouble for 43 days. And now you're refusing to pay the balance. You wrote, "I am happy to leave it with you again until it is paid off and in working order," but I don't want your amp taking up space in my home while I'm waiting to be paid. California allows me to liquidate assets that have gone unpaid for 90 days, but I don't want the hassle. You also wrote, "I was expecting an estimate when I dropped it off with you." I spelled out my rate, but it's impossible to make an estimate without opening the amp and figuring out what's wrong. For example, the speaker was hanging by a single, frozen nut that had to be cut off--no way to estimate that. As mentioned above, I was as thrifty as possible with the repairs, and even found a way to save time and money for you. I will be happy to look at the amp again after you have paid the balance, as would be the case for an auto mechanic, electrician, plumber, or any other tradesperson in town.
Do I get any points for not saying, "F U very much"?
