Unable to get Vitality Drive to work despite months of paying for it

Vitality drive device installed over 2 months ago and 2 months of vitality drive fees paid and system does not work and never has, cant access on app or on line. Numerous calls and emails to discovery to resolve , broker tried same and ZERO resolution from Discovery. Get calls about system down and having to manually upload the profile and excuse after excuse but after 2 months Ive had enough and now trying to cancel vitality drive plus my discovery car insurance as whats the point fo paying for a product that doesn't work and I cant use? Next problem is no one reads or responds to their email so i cant even cancel the product due to the incompetence at an administrative level within Discovery. At wits end and as of today Ive been paying for something that doesn't work for over 2 months, unable to get anyone at Discovery to take responsibility to fix and find it impossible to cancel. what kind of business is this .? Think its time to also cancel my medical insurance as I clearly mean nothing to them as a client with multiple products and fell for their reputation as a leader in survice in this country/
