TCS hiring - worked at a company for 5 months, and I don't have anything from that company, like relieving and experience

Hello All, I worked at a company for 5 months, and I don't have anything from that company, like relieving and experience. I also don't show those 5 months in my experience, but my PF contribution reflects on my PF account. When I mentioned the same to TCS, they said it doesn't matter if I discard the experience, as it is on PF. You have to provide the experience and reliving letter from them.
Is there any workaround or something because I cannot get the relieving from that company.
