Disappearance of my data

Hi,<br> <br> Every month when my data for the new month is loaded I lose 2 Gb data overnight. During the last week of September I topped up my data account with 3 gig. When I checked yesterday, 30 September, I still had 2,65 gig over. When I checked this morning my Vodacom app shows I only have 5,65 gig. This is not the first time this has happened since I took out this contract. This contract is only three months old and I have regretted cancelling my MTN data account from day one of joining Vodacom data. It is also one big hassle to top up this account. Why does Vodacom have top up accounts if they make it so user unfriendly to top up. You do realize that the only way I can top up this contract is by physically going into a Vodacom store, have the SIM card removed and loading data that way. Why do I even have a Vodacom app connecting all my devices if I cannot buy data for my top up contract over the net? Sorry Vodacom your service in this case sucks considering that you are not the cheapest service provider. I expected better service.
