Impossible to top up data

Every time I need to top up my Telkom Mobile LTE Daya I need to phone in. I have the Telkom app on my phone, whenever I need to login to top up data I get a “error retrieving your data” message, I try USSD - another error message, I try the online oob page when I open my browser, sometimes I get all the way to selecting the top up bundle and then the page hangs, sometimes I don’t even get to that page, I try the self help option to load data when I phone in, it cuts me off. Today I have been holding the line for 20 minutes and still couldn’t get through to a consultant. Seems like it is impossible to help yourself when you want to top up and even harder to get someone to help you.
