Cellc Failed me twice in one week

I bought airtime of R280 last week Monday and I was told that, they are busy with maintenance it will be sorted out by Thursday. Thursday when I called ( I spoke to Sibongile)I was told that they are aware of the issue but it will be sorted. Now I called again(Ntokozo answered) told me that all that airtime was eaten by Subscribers yet I only use this sim card for router and I never connected it since I saw the problem. I'm not pleased with what happened. I also bought daily 1gb on Tuesday and it was never loaded
