MTN not providing the data as per the signed package

My name is Danielle La Grange. In July this year i upgraded with a Huawei P9 package MTNCoice + Talk with MTN direct. The package was for 200 min + 200sms's and 500MB of data and 10 GB data for the first three month. Up on until today i have not received the 500MB of data as i was suppose to get. I have logged two queries with MTN i August regarding the issue but have not receive any response from them what so ever. The reference numbers for the complaints is 1- ********** 1594 & 1- ********** 9504.
