MTN *****ING DATA

On the 17th February 2020 at 09h03 i received my monthly top up with MTN which says "you have been crecited with 2GB data,150 minutes and 100 SMS", then at at 09h14 i received a second SMS from MTN saying "you have been credited with a 1 GB Data Booster bundle" and that i needed to check my balance, now me checking my balance is surprised to see that i only have 1,99GB and not the 2.99GB .MTN for howlong has this been going on,Simple math 2+1=3 so please explain to me how i only see 1.99GB, I have been on Wi-Fi since 08h30 this morning and my data is off as well so this makes absolutely no sense at all. How long have you guys been doing this ,am i one of many customers?Yet you guys are fighting your data prices but you absolutely dont care about us customers
