You can also bump it slightly to 50-60 sat/byte and wait a few more hours.
A few more hours till morning GMT time maybe, if he's lucky, a 60sat/b transaction would have to wait 3 hours to get confirmed with no new transaction hitting the mempool during all that time and we still have about one hour left of the usual daily usage peak, there are 7 blocks in the queue with over 150sat/b , it's better to forget about it and see what the weekend brings.
Really bad times to try to send coins, it's the first time I see mempool.space purging low fee transactions from its node.
I don't think the OP need to use any transaction accelerator, the last time I checked this accelerator service shouldn'r be trust and it better to bump the tx Fee.
ViaBtc works, it has worked for hundreds of members and I've used it just two days ago and managed to get one tx confirmed in a block mined by them.
So, what happened when you used it that made you think you should not trust it?
