Smart Shopper Store Account - Credit doesn't update !!!

I am so frustrated with Pick n Pay Customer Service as no one knows what' going on there. I have a store account and my credit is not been updated , 3 weeks ago I was told that its because my smart shopper is old and I need to go into a store to get a new card and then link the Store Account...that process took 3 hrs in the store as no there knew what was going on. After that I was assured my new smart shopper was linked and I could purchase online but I need to wait a day or so that the credit on my store card is updated.

Then 2 days later trying again to purchase online using my Store Account, my credit was still not updated. After an hr with Customer Services I was told to delete my app on my phone and reinstall so that my credit can be updated, done that and nothing. Then I was told that its not working probably because they online system is down.

I just want to purchase online using my Store Account but no one at Pick n Pay can assist me!!!!!
