DATA DISPUTE

I took out a sim only data contract(10G) in MAY 2019, everything went fine June I received my data it lasted me for almost a month cool. I received the data no win July again around the 12th my data was about 5G bare in mind its my only phone that use the data. On the 14th my data is all gone my applications are restricted, I use the same sites I use on a daily basis Facebook, WhatsApp and Instagram. called Telkom call customer services and was told I was connected from 9am till 12:00(not sure of the exact time) and in a space of 3hours my data is all gone they even advised they cannot escalate the issue for me I must just check on data usage which some of my applications are restricted I do not even download huge files , I don't understand how my data can just disappear like that, its mid month and I need the data hence I took out the contract to save, not to be ****** from. I am a new client but if this is the kind of service Telkom renders then I am disappointed. I do not want a lot from Telkom I want my data back that's it. Number in question : ***
