Vodacom *******

On the 28th of February 2015 I purchase a 1 gig data bundle at 8.30pm I received a message stating that the bundle was active at 10.30pm my call limit of R100 was reached and my phone was cut - meaning it is out of order. At 10am the next day I phoned Vodacom to put another 100 rand on the phone so it can be unlocked. The people at Vodacom call centre told me I need to pay R1000 to unlock my phone as I had used out of bundle rates and that was at 12 o clock!!! When my phone was soft locked and I was asleep I am so sick of Vodacoms mistakes!! Someone needs to explain and answer!!! As I am needing my phoned unlocked and I am not paying R1000..!!
