So I have two student loans with Wells Fargo, they have one account number. I frequently pay bills with Mint Bills and have never had an issue before, however I had never made a payment to this particular account. I get paid on the 15th and my loan payment is due the 18th. I scheduled the bill to be paid on the 15th through mint. I saw the money come out of my Bofa account on the 16th and thought everything was fine, as on my statement it says "mint bills Wells Fargo" or something along those lines. So yesterday, the 18th, I log on to Wells Fargo to make sure it's done, and it said nothing has been paid. Long story short, I contact mint and tell them no payment is showing up. They say it went through fine I their end. So together we conference Wells Fargo, and they say they don't have any record of a payment at all. They both are supposed to be checking back offices and wells said I had a 10 day grace period on the loan so I won't get a late fee. 
I'm just wondering if anyone has experienced this before. I'm not sure who is at fault but I would guess Wells Fargo, only because their student loan system is a nightmare and no one seems to know what they are doing as it is. Does anyone have any advice on anything else I can do to make sure I either get my money back or the payment goes through?? Thanks!
