expiry of data bought due to vodacom's error

I have contacted vodacom today as i I had to purchase data as they just took all my data away. Now we are getting penalized as we had to buy data to work this morning now we won't use all data before expiry as just bought data so now we pay double for expiring data. Please advise as this is out right *******. See eventual response from vodacom and my query . we should be refunded the data bought today or expiry date extended as now we have double data and will loss it due to vodacom policy. If they did not mess up no data will be needed. Hi Jenny. Data bundles follow a last in first out rule where the last bundle purchased will be used first.
