Medlife — 5-8 spam calls and n number of promotional messages

Wrote a review with 1 star rating (no option to give anything lesser) on app store regarding n number of spam calls. They replied asking me to send a mail to apps.[protected]@medlife.com. Send a mail with screenshots asking them to stop calling. So far I've managed to successfully block at least 30-35 of their numbers. I got a reply before 4 days that calls would be stopped in 48 hrs. Now on 4th day, I got 8 calls!!!

They call you at least 5 times a day to ask if you need any medicines. The calls won't stop even if you request a 100 times.
