Seller cancels order after we confirm the gig, and then asks me to continue off fiverr

I contacted sellers before placing orders, and gave them all the information they needed to decide if they wanted to do the job.

The seller and I negotiated and I complied with their request to make multiple purchases. It was a transcription job of 4.5 hours and they asked me to order 4 gigs at a time, so they could do an hours work and not impact on their other jobs. I was fine with this and sent the entire file and ordered the 4 gigs.

Now I get told that the job is too long (after telling the seller upfront the time frame, what it was and how I wasn't that fussed with accuracy!) and that they can't complete it in fiverr, but happy to do it outside fiverr.

I declined their offer and cancelled the orders. I lodged a dispute through the resolution centre for each order.

Is this normal for fiverr sellers to do this?

I'm annoyed I've wasted over a week on this and had a seller jerk me around with no intent to complete the job.

I would have been happy to pay substantial gig fees for this if the seller had been upfront. Really peed off with this conduct.

Is this common?
