Telkom data ****

Yesterday I had enough data on my phone which was going to expire on the 18/05/2019, everytime when I go to sleep I switch off my mobile data and check them. I had more than a gig when I went to sleep and an hour after midnight Telkom sent me a message telling me that they've paused my internet and I am out of bundles today the I bought another bundles but can't check my balance .. Telkom service centre they were unable to assist me I have a record on my phone of about 36min and 11 second on the line for help that was useless
