No. Stop thinking like that.
Sure, every action has a consequence but you have to decide which consequences suit you better in your situation. Simple put:
- If you have lots of 5-Star with glowingly positive reviews and some clown wats to burn you over $200 you can take his review and even make him look silly in your response
- If you have no or very few reviews and this is a $15 job, get rid of this person before they can do you real damage with a scathing review.
I don’t like that it is this way at all but we can only ever play the hand we are dealt and right now you have a rock and a hard place.
Best to get rid of this person entirely if they can hurt you in any real way as the small dent a cancellation does you will be less than a negative review (probably out of spite but good luck getting CS to delete that unless they swear - even then her in the forum the other day a fellow was left for about 3 hours casting pointed personal abuse and threats).
A cancellation you can trade past far easier than a negative start rating and review unless you already have many 5 stars - which i assume you do not seeing you let this happen in the first place.
