Sending offer to a Buyer's request which hasn't explained work clearly leads to many troubles

I am new seller so I usually send offers to Buyer’s request.

I send an offer to a request which I was confident that I can complete but after Buyer accepted my offer he changed the gig’s platform still I tried to give it a shot but failed as I was not familiar with the platform’s working hence had to cancel my the gig, which put down my cancellation ratio to 50% as I have completed only one order.

P.S - How bad cancellation ratio will effect my profile ?
