what should I do ?

there're two users were trolling me and talking shit about me
they cursing me in a stupid club in my name ,I ignored them but now they talking shit about me in the Rawak club and I have no idea if they did that in other Kelab
please what should I do to stop this embarrassment and to stop them talking about me in other clubes ?
can I remove a club ? and is there anything could help me to remove the club faster than only lapor it ?
I really appreciate any help
