Operation costs differently in different regions. Advertising spend differs in different regions. You’ve moved from a region with cheap operating expenses and no ad spend to another region with more expensive operating expenses and higher ad spend. Congratulations on your move, now the cost to provide you service is different, and you’d need to pay more to cover the operating expenses + expected margin.
Alternatively, procure a local credit card (I.e. the same one you used back home), billing address (i.e the last place back home), and always do everything through a VPN back home. Then you’re at least using services from where the operating expense reflects the pricing.
This is just business, and should be expected. Food is dirt cheap back in Asia, they’re more expensive here in North America. Like it or not, if I’m living here, I need to pay the prices here. If I don’t want to pay the prices here, I can move back to Asia.
