I contested a bill with a dentist, the dentist (in Mexico) lied when given an opportunity to respond and Chase believed them. I had to re appeal the claim and Chase bungled it by paying the dentist before my expert opinion had arrived to them. Chase then took 1 year and 5 months to respond as to why they paid the extremely bad dentist (15 other complaints on internet at same time period) by saying that my re-appeal had arrived late – not true. It arrived 4 days before the deadline – Chase imposed! They will now not be responsible for their error – it's time to try and get the $6,000 dentist bill and the $1,300 cost to re-appeal back from them in the courts – wish me luck! Do not go near this bank – things can go horribly wrong there.
