May I ask Vodacom to consider changing their data rollover policy? At present, when data is rolled over from a previous month, it is necessary to exhaust the current month before accessing the rollover amount.
I would like to suggest that you change this to using the rollover data first before using the current month allocation. I'd be happy if rollovers expired after one month to prevent building up a huge rollover amount.
The reason is that in some months when I am travelling less, I don't use much data but inevitable that is followed by a couple of months of travel. In the first month after a quiet month I have my current data plus the rollover available but if I don't get through my full current data I lose the rollover. If I do dip into the rollover, there is nothing to rollover the next month.
I realise that it means a little more data throughput and a small change to your data accounting system but you keep this information anyway.
How about it, Vodacom? A small change for you but something important for me and, I guess, some other customers.
