I'm looking for some advice, please. I have a client who is refusing to pay for the service provided.
A very long story short, I provided a service to Myriam and Amanda (not the real names) and they're refusing to pay as they say the job was not done correctly. I trust the people who did the job 100%, they have worked on identical jobs for a long time and I regularly receive phone calls/reviews about how well these three people work, have seen the work myself. There's not a doubt in my mind that the job was done perfectly.
I've been going back and forth with Myriam and Amanda about this for a few weeks now. Have tried everything I can think of to get them to pay, they have no proof at all that the job was done incorrectly (this proof would be very easy to acquire if they actually had any - literally just photos which I have already asked for a few times) and they've been extremely unpleasant to me (yelling/swearing down the phone, abusive emails and texts messages, name-calling).
I hope this is enough of an explanation. How would YOU handle this situation?
