The new ID Mobile app doesn't show account information correctly

Since ID mobile changed the app to the new one, things don’t work properly, and I am forced to reach out to customer service every month, since I am a PAYG customer. 
The balance information is not correct, whatever I see on my account is not the same what the ID Mobile staff see on their end. 
Last month I tried to top-up my account and purchase a 15GB bundle, and was unable to do that on the app and via browser access. I had to contact the customer service to get them to apply the bundle to my account. After they have done it I was still unable to see that on my account and my balance was showing £14.99. 
Now that my bundle expired, I went to top up again (manual process atm because the recurring bundles are not available on the new app) and I can see that the payment went through on my bank statement, and I received text message saying the same, but my account still doesn’t show it!! Which means I also cannot purchase the bundle because the account doesn’t recognise I actually just made a purchase and so it’s asking me to pay again. Ridiculous! 
The new app sucks big time and they’ve been so slow in making improvements to it! It’s unthinkable that I am unable to use my account properly online to manage my plan and bundles, and need to contact the customer service every time for applying bundle to my account.
