HCL Technologies — fraud in recruitment process

Address:

navalur hcl, Chennai, Tamil Nadu, 600092

I attended interview at hcl technologies chennai navalur on may 12 2019. I got selected and i have also submitted my documents but haven't received any confirmation letter. Tried reaching the hr nandhini many times but she isn't picking up. They have wasted all my time and effort. One full day of tiring interview process and now they don't respond. It's really bad and there must be some severe action to be taken against this
