CC. no, congregation does not support elders. It pays only expenses related to KH like taxes, garbage collection, and utilities. However, what I have heard from relatives in three different KH scattered in across country, either in the capital or countryside, the KH has set amount of money that should be collected for international work and support overseas operations.
CO on the other hand is supported by KHs, and I know it from Czech Republic and Slovakia. When he visits the KH the local members are paying his expenses like gasoline, and meals. This was and is a source of anger among many, it was channeled to me by my mom, siblings, niece, and aunt. All of them are going to different KH and they live as far as 300km apart. So it is not an issue for one congregation. I have relatives in Slovakia as well, but I do not have contract on them directly, so I only heard it channeled through my family. But I know my mom and my sister do not like supporting CO, and they told me explicitly that they feel he and his snobby wife is abusing/fleecing congregation(s). My mom does not have problem with donating money for her local KH. She donated a lot over the years and we put a lot of money when we build our first one in the city. However, nobody in my family feel that they should support CO for nothing
When it comes to Bethel in Prague, the case could be obtained from court responsible for Prague city district. This issue was also reported on media and it became a source of embarrassment for WT. According to police report one of the elder there was also an owner of brothel. It been 15 years or so for me to remember all the details. But eventually, Bethel in Prague was closed and CZ territory is serviced from Slovakia, which is weird considering that CZ twice that big and the facility was brand new and had better base. What I have read/heard it was a way to sweep the problem away. The issue of financial abuse were heard well in 1990's when some people donated properties to WT operation. 25 years ago, they had a nice, luxurious villa in one the best addresses in Prague. Why?
