Pathetic Money Market Service from Shoprite Group

I am extremely disappointed with the service with the service from Shoprite Kempton Park CBD. I went to Shoprite branch in CBD Kempton Park and the consultant advise that my Money Market Voucher is linked to my previous contact number and they advised that I should send my ID copy to a specific email to update the system and my contact number which I did the same Saturday. I was also told to do a follow up with their customer service Dept on *** which I also did since Saturday almost everyday until I revisited the same branch and I was told that there is nothing they can do - otherwise I must wait another 5 working days and I find the service pathetic to wait for a service to access just a mere R2500 voucher.
