OM Rewards Global error when spending

So I joined the Old Mutual rewards and referred friends and family to it I then 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 certified ID copy and proof of residence so they can fix the problem manual i sent them on the 3rd April and was adviced it will take 5 to 7 days but still same problem global error I then emailed and called I was told they have a backlog I used my airtime and data to refer and now that I have earned the points i cant redeem them currently i have about R650 and it seems like its really a fortune to get this work and redeem points am so so much disappointed as Old mutual its a big company to play around like this
