FNB Connect free mobile data bundle usage order?

[Raxi]

Is it just me, or are these bundles granted when using the FNB app, being used up in random order?

I got three free bundles from three separate transactions in December, on different days. The middle one got used up first. Then the latest one. The first one is still untouched and will expire tomorrow. This makes no sense.

I was hoping that the one expiring the soonest will be used first.

It is very confusing. I got 15GB valid for 1 month (until 23/12/2017) then a few days later I got 1GB and then a few days later another 1GB (which would expired sometime early Jan 2018). When the 15GB expired in December (I only used about 3GB of it), the other 2GB expired as well!
