Hi Fliers!

Hubby and I scheduled 8 different flights flights on AE in May and June.Hubby is AE GOLD.
On one of the last flights, when we got to HAM to check in, we were advised at the counter that hubby's seat had been canceled, but he still had the next leg of the flight from ATH to MUC, just the HAM to ATH was CXLD. After 3 phone calls to AE Customer service, with NO resolution, the counter staff reticketed his flight and issued a boarding pass and baggage tag for him, we got on the flight from HAM to ATH. That flight was on June 4th.
Here we are almost 8 weeks later after many phone calls and emails to AE customer service with no resolution still, even though I have sent them copies of both of our boarding passes and baggage tags to prove we were both on the flight. AE keeps saying he wasn't on the flight because his ticket was CXLD. We are sure someone at AE somehow CXLD his ticket for some reason but no-one seems to have an answer. We just want the flight and mileage credit for the flight that was taken.
Can anyone provide me with the contact number of someone at AE that can resolve this issue. this flight is imperative towards qualifying for his status again.

Thanks in advance!
