KreditBee — I keep getting calls from a loan provider called Kreditbee

I am receiving calls from kreditbee on a daily basis from multiple different numbers. It's an automated call asking to take a loan but I am not interested in getting any loan. They don’t have any option on their site to stop this. They keep calling me day and night irrespective of time till 10 pm, I tried contacting the support multiple times and they say they have delisted my number but still getting calls when I contacted them the other with the same issue they were asking to submit numbers list and call recordings of the same. There won't be enough time between confirming that the call itself is from kreditbee and starting recording. this is really ridiculous. they lying about delisting my number from getting calls and pretending to rest assured but this is not the case. I am depressed and going into a very bad mental state because of this harassment. Could you please help with this?
