POOR CUSTOMER SERVICE: DALISILE HLANGU

I purchased data from my account on mid-night the 25th July 2019 via my mobile app, which give issues, cause it intially deducted than reversed about twice than eventually deducted R140 for 2GB, however data was NOT loaded, i than called on the 26th July 2019, spoke to DALISILE HLANGU *** told me to email the bank statement which i did and gave me 72 hours turn around time. I made a follow up on monday 28th July 2019 spoke to DALISILE HLANGU again (i wanted to know if its the correct email) which she than sms'ed to me and she told me that my query was still under investigation, okay. So today i called and spoke another agent Peter Ledwaba, he told me NO investigation was logged, i had to start all over again now with Peter Ledwaba, which than logged the Investigate query whilst i was on the line with him, he also gave me 72 hours turn around time, i have provided all the necessary evidence ( bank statement and sms's). Is it really fair to be **** to just like that??? waste of time and effort with DALISILE.
