Bundle removed from account

Can anyone comment if they experienced vodacom data bundles which you purchased disappear from your account after you query a large out of bundle data bill? <br> <br> Case Number: S3-90I31-13MIW<br> 18/12/2015 18:33<br> <br> I had purchased a 3gig, 1gig, 1gig data bundles on top of my 1,8gig contract data with that I received R5500 data bill for out of bundle rates. Now after querying the bill my 3gig data bundle I purchased disappeared from my account as if I never purchased it in the first place. Did this happen to someone before?
