8ta data bundle usage dispute

Received the most pathetic from Telekom mobile customer service ever,so on the the 01 of April I bought 2gigs worth of data after loading the data I left my phone on the counter I use an iPhone 7plus I get the first sms that I’m left with 499mb or so of which I could not understand as I had not used the bundle yet so I went switched off mobile data then reset my mobile date so I can see if there is any app that maybe using data unusual put it back data on received a message that I have used up all my data called the customer care spoke to Lindokuhle Nkagane he told me not worry in 2hours time the back office will call me to tell me what happened to my data I asked him for a call reference and reference of my escalation he said they don’t provide that ,called again on the 4th to find out what’s going on spoke to Xolile Ndlela who told me the previous consultant didn’t log anything he will do it for me gave me reference ********** 7 and said it will take 72hours to be resolved waited no one called me so I called back the 3rd spoke to a lady who told me the call was logged but was not sent to the department that deals with queries she will email Xolile to fix that I need to wait another 72hours,today I called again spoke to Minenhle who told me my call was closed I never got an sms or call to tell me why or what happened to my data so I requested for a senior I was told she is busy her name is Nokuthula Ngozo she will call me I called around 8am waited the whole day no one has contacted me I have been happy with 8ta this was my first time ever having an issue with them and I’m shocked that they have to customer care etiquette at all,I explained to them that my data usage on the app does not correspond with what they saying and that my app background refresh and iCloud it’s not the first time of me using an iPhone I work at customer service myself and I know how to make sure I switch off certain settings,this is my last resort I need my query resolved
