5 Days - Unconfirmed Transaction on blockchain. Please help!

[Taylor.in]

I purchased bitcoins from someone from LocalBitcoins for cash. Seller took cash $2000 and sent me bitcoins from his Blockchain wallet.

Now its 5 days but the transaction is still unconfirmed. Seller has vanished and his mobile number unreachable.

Two questions:

1- can he somehow cancel this transaction or take back those coins he sent me?
2- is it normal to 5 or more days delay in transaction confirmation on 120sat/byte fees?

My transaction: https://blockchain.info/tx/371d2e702c53b40f00e760dcfc387fb83a4d583d0d332812f8f03d29705673c1

Need help, please reply. Thanks in advance!

The payer can double spend the bitcoins until the transaction has been securely mined (e.g. in six blocks). You might want to try accelerating the transaction.

1. Because he used blockchain.info, it will be dependant on them to cancel his transaction -- stop broadcasting it. Which i believe will happen after a certain amount of time, I am not sure how that process will take.

( As it is a web wallet)

2. With the current mempool the average fee is ~900 sat/b, i'd say that  with the current state of the mempool, this isn't uncommon. https://blockchain.info/charts/mempool-size

3.

You should try every hour to get your transaction into the ViaBTC accelerator, https://pool.viabtc.com/tools/txaccelerator/ as that is the only one that still works.

Note that you have approx 5-10 seconds to get your transaction in, before their limit is reached again.

Should I use their paid service at ViaBTC if you are sure it works. They are asking for payment in BCH for a transaction of BTC. Please advise. Thank you very much!
