The time seems to have come when transaction-accelerating services will start sprouting like mushrooms after rain. It can happen to anyone that a transaction gets stuck because there is a sudden jump in the number of transactions in mempool, but paying hundreds of $ to someone to supposedly speed up a transaction that would have been confirmed anyway is not a very smart move.

The transaction accelerator in question may be cooperating with several pools, but who can say with certainty that they are responsible for the confirmed transaction? If these are leading mining pools, then the waiting time would certainly not be up to 4 hours - the chances that one of such pools will not find a block in one hour are not very great.

Learn how to read mempool properly and set a fee in relation to current conditions - isn't it better to pay a few $ more than to use such expensive services?

yes totally agreed But i am only receiver , and Sender made mistake and our works done after Block chain confirmation.
Later one of my employee did Tx Booster because they use before in june 2019.
