Complaint regrading the forfeited data

The email below was sent to Vodacom Customer care on 29/01/2016 & again on 04/02/2016, To date there is no feedback<br> I did my upgrade on 16/01/2016 at Vodashop in Jubillee Mall & I was assisted by Tshepo. I specifically asked him if I upgrade will I lose my existing data & he advised that no, I will carry it over from 01/02/2016<br> Last night when I sleep, switched my phone off I had 782.36MG of data. To my surprise this morning when I check my balances I had a zero balance on my data, login the My Vodacom, still shows the same then I decided to contact the call centre where I was advised that I forfeited my data from today as I have upgraded to the new contract<br> I have the following questions to ask:<br> - How can I forfeit my data if I was advised by the Vodacom Consultant that I will carry it over from 01/02/2016?<br> - How can I forfeit my data if I can only get my airtime for the new contract on 01/02/2016?<br> - How can I forfeit my data on 29/01/2016 whereas my upgrade is effective from 01/02/2016?<br> I feel that I was advised incorrectly as to push the sales for the upgrades. <br> I have been a Vodacom customer for years & I have existing 3 contracts & this is that I will not appreciate
