voda nada data

Suddenly my data depleted. Very strange seeing that this has never happened before. Anyways, I loaded 500 mb which depleted in 3 seconds, next day another 500 mb and guess what- ****! gone instantly. Auto update is not active. Call centre blames updates, I repeat my auto update function is not activated.I am sick and tired of this type of service from my provider shame on you!<br>
