POOR customer service, no feedback - no answer!!

I'm highly disappointed with Vitality. Joining them on 1 Jan 2016.. joint discussion between Bankmed and Discovery. Before it was with Momentum. Not sure why Bankmed moved over to Discovery because so far it is just a painful experience. I cancelled my Momentum membership in December 2015, and given that the dashboard on my momentum log in details where no more available. I phoned Vitality on numerous occasions sending and resending emails, sending emails and at the end i receive confirmation from Monica Phaweng in an email that the screen shot from Momentum in November confirming my status as Platinum which means I should be Gold with Vitality. But they put my status as BLUE which is incorrect. I tried how many times to call, and correct that, but with no hope. IS THERE ANYONE AT DISCOVERY WHO CAN HELP ME TO GET THIS SORTED AS IT SEEMS MONICA PHAWENG IS JUST NOT GETTING ANY EMAILS FROM ME OR DOES NOT BOTHER TO GET THIS SORTED FOR ME! Going the extra mile to help is surely not important for Discovery at all. Very disappointed, and tired of the struggle!! Everytime you speak to someone new, you hear a different story! Sad but true. Can someone from Management in Discovery contact me
