I was banned from a certain client when I gave 2 weeks notice on rescheduling an easy to fill shop. Is this a common or acceptable practice?

maybe they have a lot of shoppers who live nearby who can easily do it. Don't know if it's common though.

It’s not really common if it’s your first reschedule I would reach out to them and ask to try again.

Sorry to hear that Kevin, hopefully you find a remedy to your situation.

Very sad, but often times when you cancel a shop, especially if its your first one with an MSP, they frown upon that and decline/delete you from their system. Its rare, but it does happen.
