SLOW LTE faulty app terrible service!

I got an LTE Telkom data deal in December 2017 for the first few months it worked just fine, now for the last month its been terribly SLOW and the Telkom app data use section does not work anymore also for more than a month. I've tried the self-help service on the app today and was told by Mashudu Mulaudzi who just said our systems are responding very slowly and ended the conversation there. Then on my third attempt, Mpho Kgotleleo just said please contact 081 180 and ended the conversation. I called 081 180 and held on for ages with no answer. So the app doesn't work very SLOW internet LTE speed and terrible customer services. This is not what I'm paying for I'm paying for fast LTE, not dial-up speed!
