It's the vulture capitalists and boards of directors to blame for this shit. It's always about maximizing profits and minimizing costs, no matter what the consequences are. I thankfully have had decent luck myself with the customer service groups that I've dealt with but we don't have many different things like you do. I think we might diversify a little bit for a few reasons but hoping to keep the same card company since it's helped us well enough so far.
It's crazy and sad that these countries get or use equipment that is obsolete in countries like America or European ones and have to support everything based on that.
