Axio credit bill generation

I purchased a health insurance for my parents through policy bazaar and they arranged a no cost emi setup through axio and Karur vyasa bank. The axio app used to generate bills regularly and I last payed my bill on 16th December,with last date to pay was January 5th. But no bill was generated after this. I don't know if it's a technical glitch. I chatted with the axio chat bot and it said I will get the next bill on 16th February. What about my bill for January? Can anyone help?
