Grofers — Money laundering and no complaint handling

I want to raise to consumer forum that grophers has no formal complaints process and for everything, they will take a feedback and ask if there is anything else. They don't care about complaints. Second is that I feel they are laundering customer money because they take orders and then ever time there is a refund for items unavailable but the could not tell us at the time of order. They are misusing customer money and we cannot be sure if something you're ordering will be delivered or not, that's how bad their management is. I've raised this before and no one got back to me or this has been improved. I demand redressal for my time and efforts and investigation for their practices that lead to money laundering.
