Got No longer into consideration after submitting documents just WTF!!!!!

I had booked a slot for the 2nd round, they did not confirm, i kept rescheduling for the next 3 weeks, 4th week i get no longer into consideration, the next week i am asked again to submit payslip and id proof, the job was in interview again with new job id,i saw that 4 inactive jobs for same position but different job ids, yesterday they again put my latest job(same job but different job id) into no longer into consideration, i do not have any HRs number all the communication happened via email.
i don't know what to do, i had applied for this role on 21st April now its 22nd June just WTF!!!!,
i was relying on this job i did not apply anywhere as i had medical emergency and had to work on my current JOB.
i mean i just wasted my 2 months
