Weekly limit

Has anyone experienced a drastic reduction in their weekly limit?  I’m playing in the Megopolis league and my limit was reduced from 390,000 to 198,000. I am hitting that limit in the first 2 days and then I’m out. I can no longer earn rewards for a full 4 days. Doesn’t seem fair. I reported it to customer service and they told me they couldn’t do anything about it. I’m very frustrated.
