JPMorgan Chase & Co. Money Transfers Complaint

Domestic (US) money transfer Other transaction issues California

As a favor to a friend, I setup a Chase Quick Pay account linked to my credit union checking account. This person 's relatives would send money through Chase Quick Pay where I would get an email to login and to accept this money. I would do so and after 1-2 days, the money would show up in my checking account. I would then proceed to withdraw that money for the person it was intended for. The last transfer for $170.00 was deposited to my checking account on -/-/2016. I noticed today however, that the money was reversed by Chase and taking from my account on -/-/2016. I would assume that once the money was transferred and deposited, that the other party could not cancel the payment. Further, I would assume that once Chase makes the transfer, the money being transferred has been verified and is available. I do not understand how Chase can come back a week later and remove that money from my checking account without me agreeing to it. Also, if that money was not available, why is Chase even making the transfer to begin with. I feel I was scammed both by the person making the transfer and Chase.
