Data query

I have been struggling for the past week with Telkom and have received no assistance. I cannot use the 20G Telkom data that I received. The data will be expiring at the end of this month and I can't use it. Everytime I call the agents tell me the same thing, they provide settings but I still cannot use the data. This is pathetic and I regret renewing my contact with Telkom, I have been a loyal customer for years but can't get any assistance. I am not happy. I hope someone can assist.
