Product: Payday loan, title loan, personal loan, or advance loan

I took out a loan with Goodleap that disbursed on XX/XX/XXXX in the amount of {$10000.00} at a rate of 13.49 % interest. At the time of application key information including daily interest computation, required third party data collection, information sharing etc was not disclosed. Upon seeing these requirements after recieving an email telling me my online account was ready to be activate it was implied i had no other method of payment or communication than via the website. I immediately file a HEL through my credit union to repay this debt. Statements from Goodleap did not show any accrued interest or how payments were applied simply showing a principal balance and interest rates. I made an online payment of XXXX on XX/XX/XXXX twelve days in advance of first payment due. No statement or bill was received via paper means/mail until 3 days after the first payment was to be paid. The statement said it was generated on XX/XX/XXXX Payment Due was XX/XX/XXXX yet it was not received until XX/XX/XXXX. My HEL to pay off this loan was received XX/XX/XXXX at which time I called for an immediate payoff figure not a XXXX. The agent claimed a payoff amount XXXX. When I calculated the interest that should have accrued having never made a payment prior this number was still too high. I immediately brought this to the attention of the representative and asked for a full accounting and/or amortization schedule show interest accrual for which i was told they can not provide that as interest is accrued daily these documents do not exist. When I then informed them that their math does not match the calculations of my interest rate on a daily computation I was told this was what i owed. I requested to speak to a manager who first identified themselves as XXXX and then later as XXXX. I explained the situation again and that I have a background in banking and mathematics and that the numbers they were quoting did not match the rates or agreements and again asked for a full break down of the account with all interest accruals. During discussions about how the numbers did not match the interest accruals quoted by the manager changed or did not match the claimed payoff amounts they quoted and only after it was stated that I would be filing complaints with XXXX, CFPB and other agencies was any supposed interest accrual provide but it was simply totals at time i made first payment and total since then and these numbers still did not match the managers claimed daily interest rates. I made total payments in the amount {$11000.00} to pay this loan in full calculating interest of $ XXXX as if no previous payment had been made and was told this would be insufficient and I could still be billed in the future. I have filed a complaint with the XXXX  seeking resolution with a full accounting of this loan, its interest accrual, payments and proof the loan is closed as paid in full with any and all liens/interest in property terminated with proof of such. I also request no further contact from this company in any matter. Upon researching online there are numerous complaints regarding similiar issues with this company and it has used at least 6 previous addresses in XXXX, XXXX and XXXX  in addition to their recent change to a XXXX XXXX currently being used out of XXXXXXXX XXXX
