Discovery Vitality - pathetic service!!!

I have never been in favour of publicly complaining or naming and shaming - but discovery Vitality help desk has given me no option! Over a month a ago, my husband and downloaded two vitality vouchers worth R1000 with our discovery miles to purchase an item I really wanted for winter from Cape Union Mart. I stood in a busy que with my item, just to find out that the downloaded vouchers were invalid! Embarrassingly, the cashier had to call the manager to cancel the transaction so that other clients can be helped while we wait to try again. No joy on the 2nd or third time. The store had their IT dept on the line but unfortunately they could not assist. They suggested I call discovery vitality to try and get it resolved —— this is where the nightmare started! Firstly - trying to use google to get a direct number for the helpdesk took 30 mins of my time, landing up in call centers for insurance and medical, until I finally managed to get through to the vitality call centre. After holding for 10mins, I finally got through to someone who gave me a Ref number and promised feedback within 3 working days (which I said was ridiculously long! ) This call took 27mins - just to be told to wait another 3 day’s. So.. 3 days went past - nothing from vitality! I once again contacted them and was told that they did attempt to call me (their number is clearly marked as Spam which my phone rejects). Why not email me? Or leave a message???! Anyways.. another 25min call only resulted in more promises and excuses that technical is dealing with it blah blah blah. So.. nothing once again from discovery until I make another call the next Tuesday and insist on speaking to a customer services manager - complete waste of time - they had the audacity to blame Cape Union Mart for the voucher not working!!! Long story short - over 3 weeks later - they finally re-Imbursed our discovery miles to download again for vouchers. So.. Vouchers downloaded again and off to cape union mart I go to get that jacket I wanted 4weeks ago! The manager saw me and was shocked that discovery took over 3weeks to sort it out! So.. stood in the que again with my item and guess what!! The vouchers are invalid!!! Again! Cape union Mart immediately got hold of their team to investigate. Being a late Saturday afternoon - I knew trying to contact discovery would be a waste of time! Cape union Mart contacted me after 5 that afternoon just to apologise for not having some feedback for me yet. Then they called on Sunday to let me know that their IT has investigated and the voucher numbers are too long and invalid! Soooo... Monday comes, another 25min call to vitality, another two reference numbers received with empty promises that they will get this resolved.... guess what - it is now Saturday again and nothing from Discovery vitality!!!! Guess I have to wait for their office hours again and prepare for another 30min call! Pathetic guys! Absolutely pathetic! Please do not offer a service that you are not able to deliver!! Give our 1000 miles back ... I don’t even want the stupid jacket anymore - it is almost summer now after all this time and it will remind me of this horrible experience!!
