10GB Telkom On-net campaign data

I just want to share my thoughts on my experience with Telkom mobile for the past few weeks as I have been receiving the 10GB campaign data for the past few months as the wifi hotspot had ended and was receiving 10GB On-net data every month from July until the end of my contract,yet recently the data that was loaded onto my account on the 27th September which is suppose to last for 30 days, but to my astonishment when I checked my balance and the data was only valid for 7 days even though the text I received stated 30 days,l have been in contact with the customer service department since 03 October and spoke to more than 8 people and they couldn't assist me at all, it was as if they didn't know what to do at all, I eventually went to one of the Telkom mobile stores on 4 October and they logged a fault for me under Case no:*** as I showed them all the texts and screenshots of the data that I received, I really hope this issue gets sorted out ASAP as this has been a huge inconvenience.
