I've never had that type of issue with a Chase cc, but I did take them up on a 1.5% cc special promotion until the balance was paid off. The terms were 2% minimum monthly of the outstanding balance. Based on that, I did some home improvements and gifted my daughter $10,000 for helping her purchase a home.
When the recession hit, Chase couldn't up the interest rate, but they could change the minimum percentage due, that went to 5%. My monthly went from about $500 to about $1,250 with no notice. They were still sending me these "special" offers up until 30 days before changing the minimum % due. I was able to handle it but reading the website, complaints, many were not and had to negotiate higher rates for lower minimums to keep from defaulting.
Chase did this in the height of the recession when many were and still are struggling. Chase is not a bank I would feel comfortable trusting as a business/financial partner.
