I completely sympathize with you. My wife and I had floors with EMPIRE installed in December 2012. We put $5500 down and finananced $7500 thru Wells Fargo. They have been an absolute nightmare to deal with customer service wise and it seems that they have an issue with whether we pay on time, pay to early and even if we send them more than minimum balance at one time. Our payments are $228 a month and one month we sent them a $1000 in between the start of the next billing cycle and they actually assessed our account with a $35 fee! For making an extra payment! We haduntil December 28th to pay the bill off in full before the No Interest promotion kicks in. We finally had enough of their nonsense and went to our credit union and got a personal loan at 8% to pay them off in full today. There are too many loopholes with their agreement and there's no way I'm giving them the satisfaction of hitting us with $1800 in interest in the event we can't pay off this account on time.
BTW: Our floors from EMPIRE are amazing!
Wells Fargo not so much...
