Lost data

I bought the LTE data on the 07/08/2020 and the data misteriously dissappeared the next day, called telkom customer care line 081 180 and their response is that there is a three days investigation, asked what am I suppose to use while waiting for their response ,the guarantees I have that the next data I will purchase will not disappear like the first one and if there is a refund policy in place for such matters, the call centre agent didnt have much response asked to speak to the supervisor or Cc me on her email she will sent to her supervisor, she informed me that their policy doesnt allow clients to be Cc'd , she gave me her team leaders email address which ***.

It's not fair that data disappears out of the blue and I have to wait for 3 days or buy data again.
