INSURANCE CLAIM AND CREDIT CARD

My husband was diagnosed with cancer and we have a policy on his credit card that covers dreaded deceases. We logged a claim and it was paid out. But then only two days after the payout we used the card and the card was suspended with immediate affect and we had to phone the call center. Once he did that he was transferred to three people only to be told that his card is suspended because he is unemployed. He tried to explain this to the call center but had not luck. He ended this call and I wrote an e-mail to the claims department which I dealt with before and the lady Sherria Munsami has not responded to my mail. We have this card for many a year, have not defaulted on any payment, logged a legal claim, was paid out and this is how you treat people. UNACCEPTABLE.
