Poor customer service

It appears that's my sim contract of 60GB anytime data and 30GB Night has expired.

However Vodacom did not have the courtesy to notify me of such until I noticed out of promotion deal billing. Data has been allocated in the least beneficial way to me as 30GB anytime and 30 GB Night at almost R700.

I do not think this is fair to be billed an exorbitant amount without being notified of such and given alternatives or the option to upgrade prior to expiration date.
