Paying for what you do not receive

Since starting my contract I have been noticing that I do not receive my package as per the contract I have signed. Unfortunately I didn't keep track as I have done now. 17th every month I receive my package, which is supposed to be 1.5 GB night express, 1.5 GB Anytime data, 150 SMS's, 200 Anytime minutes. As per the consultant when I did my upgrade said that anything left over will roll to the next month. Roll over is only for 1 month with current month. At the end of day 16th Dec 2019 I had the following: 73.27 Anytime minutes Airtime 96.94, SMS's 957, Data 712.44 MB - Recurring Made for Me. With package for new month only received the following and minimal roll over 1.5GB Anytime data with roll over of only 500MB, where is the difference of 212.44 MB, 200 Anytime minutes with roll over of 73.27 , SMS's 300 includes roll over 150 and current month Did not receive 1.5 GB night express

My expectation that the roll over rule needs to apply for the data, so additional 212.44 MB to be added to data and that I receive my 1.5 GB night express.

You more than welcome to call me, if my query doesn't make sense.
