I think you need a third, decider punt, for a fair judgment 😉
I found Cindy to be an excellent provider but also the more human out of the bunch I’ve been with, so although very unprofessional and disappointing for a paying customer, I think I’d expect such behaviour from her, but I don’t justify it by all means. Like if I was her and I had a moment I’d try to find a different arrangement with the client to make up for the underwhelming performance.
