Medlife — Constant spam calls and very late delivery

After complaining dozens of time for unregister my number, as they call 3 to 4 times every day during my work hours and disturbing me during my important work calls, they still call me everyday. This is just ridiculous of their services and want to really move ahead a file a case for mental harassment on medlife. They have crossed the limit. I nearly lost my client due to such spam calls for their stupid offers.
