From pillar to post for itemised billing

I have been sent from pillar to post for itemised billing for a prepaid number. I went to the Vodacom store in Brooklyn to request for itemised billing for the month of September 2018. They told me they can't assist me and I should call customer care. Customer care referred me back to the store, who still turned me away. I tried to get it by logging on online but only allows you to get up to 30 days. I then tried to go through online support (live chat). I ended up chatting to someone called Jenelle who did a security verification and then she confirmed that the itemised billing will be e-mailed to me by today. I have been checking my inbox NOTHING!!! I went back onto the live chat platform and chatted to someone called Nkululeko who referred me back to customer care. WHAT IS GOING ON VODACOM. Can it be that hard to get itemised billing for 1 month?
