POS and App integration issues!!!!

Good day

I've paid my account in full (R1346.73), on the 13th of Feb2020, after which the App on my phone was updated to reflect the following: - R0.00 current balance - R1680.00 credit available - R0.00 due this month

On 23Feb2020 I was in Mr. Price Home Tygervalley to purchase goods and was surprised when the cashier told me I have to pay in R900 seeing that I don't have enough credit available on my Mr.P account.

He went into my account and can confirm that I've paid my account. How is this possible? It was quite embarrassing to stand there - having to leave everything I planned to purchase.

I've decided to wait a few days, but then AGAIN, when going on the App today, selecting the goods I want to purchase, when checking out with a total of R659.94 - it says available credit R540.05.

How is this possible - how can the app and your POS not talk to each other, and how can the app say I have R1680 credit available, and then can't even make a purchase of R659.94???

This is rather frustrating - twice I'm not able to purchase goods, once in store, and now on the app.

Please can this be sorted and feedback be given asap!!
