Old mutual rewards global error

I joined this old mutual rewards program ..I referred friends and family to it...I tried to reedem my points for vouchers it kept on saying global error ...I contacted the rewards department and I was told to email my ID copy and proof of residence so they can fix the problem ..I did that..I was rep**** that they received my documents and it will take 5 to 7 working days to fix the problem ...ok day 7 still same problem global error ..I emailed and called I was told they had a faulty system which made a tinny backlog ...I checked after a day I was told no reply has been received from the verification department ... I asked them to do follow up ... I called next day I was told that they need to verify all my refererals...each day is a new story ....I used my time and data to refer and now that I have earned the points it's. Struggle to use them ..I have about R1560 in that account and seems like many of us have the same problem
