accurate information from the app with compuscan

Im a capitec customer all my accounts are updated , but when i apply for credit facility via app only tell me that my credit score is week according to compuscan. I was wondering how come this happens since my credit score has improved from 627 to 637 at the curent month of july 2020, I have noticed that Capitec bank credit rating system is improper, outdated, misleading and really disfunctional. i have online short term loan (6 month) with capitec that ap**** around may charged 60% interest and the account is up to date but when i check credit facility via app for new/upgrate credit/loan the result from the app is desapointing as reflect that my credit score is week according compuscan but when loged in to compuscan to check my credit score is sithing on ( 637 average ). On it was a shock of my life to learn the capitec app credit system reflect (Your credit rating is weak) this is so inconsistence with the credit report dated 07 july 2020 (compuscan) in my possession which shows my credit score of 637 (average rating). This is so disturbing why capitec reflect weak adverse report yet all my accounts according to credit beaurau compuscan have no adverse data. My question is why capitec does not update their systems time to time? How many consumers suffer through this carelessness of capitec bank which disadvantage us as consumers to qualify for adequate credit facilities but due to this inconsistance disadvantage us? Please i need answers.
