Medlife — irritating messages whole day

I want to delete my medlife account permanently but there's no any option of deleting account in medlife page or app. I receive 5-10 delayed delivery apology messages, promotional and ads text messages from medlife and it irritating ad frustating.

Please do something needful as early as possible.

I can give my mobile number where i get messages from medlife.

Kindly confirm me once done.

Thanks
