Poor service from Telkom Call Centre ***

I took out a contract with Telkom 2019 with 10 GB When the sim card is put into any device it shows " Out of bundles" It was working before. I phoned *** on 24th October and David confirmed that I do have 20G because it was brought over from the previous month. Service still fine. We still don't get any data. I phoned *** again and spoke to Nko 25 October at 8:32. She took her time to confirm my personal detail and after giving me the device contact number asked me to hold to check how much data I do have. I phoned from my cellphone and checked the time, it was 11:46. At 15:40 she confirmed what I do have 20 G. When she wants to confirm my address after she already confirmed details and gave me the contact number of the device with the 20G. I asked her to speak to her manager or supervisor. She said hold I am going to look for her. I hold till I saw my minutes stand on 20:57 and dropped the phone. Poor service and my problem still has not been solved.
