Horrible and pathetic service ever

I have had the worst experience I have been going back and forth with Discovery since August 2020 wrt my vitality. So I’m November 12 i re registered for full vitality since vita active was useless for me. And mind you been with Discovery since 2917 and never I have received reminders for my yearly medical check ups. Now the 1 December 2020 I was to be migrated to full vitality what if I tell you that even up to day I’m still on vitality active with multiple reference numbers for this enquiry but still not resolved last week they just threw me with an email with no explanation that I must re fill in my life insurance documents even after been told we will redo this and give you a callback. Basically I have lost 8 months of full vitality benefits and forfeited the 3 months trial. Funny enough my vitality was on full vitality in December 2020 as I had accumulated points for my vitality marked items at woolies and I could see my cards etc. Then boom I was back on vitality active. So I’m the 12 February Friday 2021 I was also promo a R200 voucher that was to be active for the next Friday 26 February 2020 that is still maybe still also playing Marbles and hide and seek on its way. Like the activation of my full vitality. I’m not sure what I can do to resolve this as I can’t even work in to their centres to resolve this
