No TCF, Horrible Customer Service

I took out a 20GB Day & 20GB Night Contract and upgraded to 30Gig Day & 30Gig Night but this Month I got a total of 30GB instead of 60Gig and I did call about this the very same day(12th) and was told that you know about it as there is an issue and are working on it. I was told I would receive the balance 30GB but still haven't and I'm running out of Data now, please urgently assist🙏🏿🙏🏿🙏🏿

*it's the 2nd time this happens and the last time it took forever to get the balance, so please look it into so it doesn't happen again. . .Thanks.
