Where is the data?

My daughter was in Mozambique for ten days and she used a different SIM card whilst she was there. Upon her return her data was depleted? This is not the first time either! What is going on? Are there other SIM cards being produced? Sounds very suspicious! Also I enquired as to why my account was more each month. Each time I had to open my line the R50 continues to be added each month until it's cancelled. What a ****! It is a once off amount only added on to open the line. This has happened with my number and my daughters. Please refund all this ******* amounts and all the data **********ly removed from her account
