Dude, that's horrible. I'm sorry to hear this.

I'm not sure what the funeral/burial industry is like in your country, but over here they try to charge you excessively for anything burial related (like what this guy is talking about on YT). They take advantage of families that are grieving so that their businesses can make more money.

If it's anything like that over there, take a moment to really review how you can have the lowest cost funeral possible, and designate a family member to help your parents ensure that they aren't taken advantage of with the process.

Good luck - I wish you the best.
