No Service - bad service

When I load 5G data, I get 5G midnight surf data. Last week when I wanted to use my Midnight data it used my all my Once-Off All Network Data. When I phone to ask them why this is happening they made me feel that all of this was my fault, not their fault. Then the man said I need to phone them at the time I am using the midnight data so between 12am till 7am. Now I have my 73-year-old mother that is staying with me, now I need to wake her to speak to Telkom to sort out there fault not mine. I reloaded data again with a 100G data for midnight use. Now I worked the weekend, but when I used it last night it used all my Once-Off All Network Data. So, I phone Telkom at 02:14am and again 03:04am, both times they said that because of the lock down the call centre is closed. How can’t the man that I spoke to last week tell me that? They do not know what is going on in their company. So, I phone this morning and spoke to a lady told her wat I did and said I want my data back this is not my fault anymore. I have done what they told me to do. Now I can’t work…. I wonder if this happens to them if they will be ok with the service they get. And if one person asks me again, I your roaming off, I will scream!!!!!!!!! All I want is my data back and they can take if from my midnight data, but no they can’t. I do not have any money to buy more data anymore, and why do I have to pay for their mistake???
