Company asking for bank statement!!?

I'm 20F, and gave an interview for a sales job in a company from London that sells digital marketing services and social media management services. they even have a software that they want me to promote. for every client i get them i get 10 percent commission. my role is to find the leads, convert them , close the deals, and give progress report everyday.

the thing is i e-signed the job contract, it was valid, nothing fishy or trap written. i got hired. now on the second day of my job they are asking me for my bank statement and emergency contact number.

I'm from india. i live in india and this is a part time remote job i applied for. i already do a full time job. and i did reveal this to them. i gave them my masked aadhar card when they asked for ID proof.

is it safe to share my bank statement??? and emergency number??? can i say no to both??

i don't wanna share either of this. not my emergency number because I don't want to involve anyone else from my life into this. and bank statement just sounds very fishy.

pls tell me. what to do help
