You should have informed this sender about the fees anyways, The fee was too low for viabtc thats why I quequed it up on
https://confirmtx.com/. It should take 4-5 hours to receive confirmation/s
There are also other services that can help you confirm this such as Coolwave's
https://bitcointalk.org/index.php?topic=2204426.0. If you want your transaction to be prioritized, better talk to them and see if you could have an agreement since you said you can pay.
