1. This is the sad outcome of the alignment of HR with Business. In many companies where HR is too aligned with business, they loose their own independence and identity. I am sure your reporting manager's connivance is also there.
2. One question, did they formally accept your resignation and conveyed to you to you their acceptance formally?
3. First speak to the concerned HR Head of the past Company, if they issue the RL immediately then no issues, if they do not issue then write an email to HR of your former company with cc to CEO, your erstwhile manager and your current manager also. Explain complete facts without making any negative comments or undertones, also explain your necessity of relieving letter quote the exit clause fully from your appointment order/letter. Request for immediate issue.
4. Wait for 7 days, if you do not get the letter contact a good advocate who deals in such matters and take a legal recourse.

Usually it happens in many HR leaving the organization , So while leaving you need to have clearance and hand over copy. so that tomorrow if they say handover of things is not properly and they might put a blame on you. if you have done it while leaving & having a copy then you can request first as per others opinion . If its not been done still they are playing around you talk with respective labor department to resolve this concern.
