Communication tactics: Debt collection

American Express has contacted me numerous times from various phone numbers regarding this debt. I previously agreed to a payment arrangement ; however, that arrangement was subsequently canceled. Since then, the frequency of collection calls has become excessive. I have informed American Express representatives that I have been dealing with a serious illness, yet there appeared to be little consideration given to my circumstances. Despite my efforts to communicate and address the matter, the calls have continued at an overwhelming rate. Additionally, my family members have informed me that they are now receiving calls from American Express regarding my account. This has caused significant distress and concern for both me and my family. I believe the volume and nature of these collection efforts have become unreasonable and have added unnecessary stress during an already difficult time.
