I have dealt with this person in the past, always paid with a check, one time a check was returned, it was a bank error as our direct deposit was mis-routed within the bank. I had my bank send a letter to this person, all was well. The next time I dealt with them a check was fine and all was well. Last time I dealt with them, they accepted my check, this was almost 8 weeks ago. Now, all of a sudden they have decided they want cash, I offered cash on the day they accepted the check. But no, a check was fine. Now, all these weeks later they are basically harrassing me about giving them cash and sort of trying to imply that they will come after me legally if I do not comply. I am certain, this is not legal , at all, the excuse, they have had several checks from others returned and their bank will no longer accept checks . I plan to send a certified letter to them asking them to cease and desist their harrassment, but I am trying to find some legal precident to list in the letter. Normally, I would have no issue exchanging the check for cash, but one, they are a ways away, so I would have to drive there, I thought about sending a postal money order, but if they are insisting on cash, I will be insisting on having my check handed back right then. This really irritates me that they have waited this long to change their mind.
