KeyBank NA Consumer Loan Complaint

KeyBank NA Consumer loan department,

Vehicle loan Managing the loan or lease New York

I applied and received a boat loan though key bank in -/-/- and it was for 15 years or - payments.Over that period I received promotional correspondence of a skip a payment promotion which I took advantage of - different times. How it worked was i would send Key Bank - dollars and they would hold that payment and add it to the end of the loan term, which in essence would make it a - payment loan as Key Bank describes it.My final payment was due this past -, which i have n't paid as of yet, Because in -/-/- Key Bank contacted me that my final payment which i thought would been the same as the other - payments of - dollars was going to be in excess of - dollars because I took advantage of the promotional skip a payment program, which they claim those - payments had been accruing interest from the time i skipped those payments.Now I do have - of these promotional letters with the mail in coupon at the bottom this promotion did not take advantage of at the time, also will attempt forward it to you in my documentation. This to me is DECEITFUL and not a promotion and consumers including myself should be aware of these slight of hand practices ... .Please help me with this situation.
