I paid the XXXX up front then when we get into XXXX facility at XXXX XXXX XXXX. The nurses offered us free flu shots. Everything was OK but later we receive the bill charged us {$1500.00}, XXXX free flu shot turned into XXXX different shots that we never received then the charge from another lady who was in hospital facility at XXXX XXXX, because she has the same name with my wife but different account number. I went down to member service show to them to complaint they recognize the errors but could not fix.!!! Later almost 2 year I receive my XXXX health insurance payment.
