Checking the 17PvS.. address, there are a number of transactions in and out. It is perhaps worth mentioning that by design, bitcoin addresses should be used just once, to help protect your financial privacy.
The transaction ID you linked is for a transaction that has been confirmed, if the funds are not appearing in your wallet then I would guess that either your wallet is out of sync with the network, or someone has hacked your wallet and stolen the coins. Considering the 17PvS.. has outgoing transactions after the transaction you linked, I fear the latter may be the case for you.
(Also, for what its worth, I would not use blockexplorer.com. They have decided to refer to bitcoin cash as bitcoin, which makes using their site very confusing. In my answer I assume you are using bitcoin, and not bitcoin cash)
We can't help you. If that company (never heard of it) does not deliver it probably means they ran away with your money. – Alex – 2018-01-19T11:10:47.660
