UNTRAINED VODACOM STAFF

These people are not fully trained. How can they tell me the notifications I am continuously receiving for numbers unknown cannot be stopped by them. I need to go to a Voda shop and ask them to assist by blocking, which in itself is utter nonsense. They are either out of depth or just purely lazy to try and resolve the matter. The more I complain the less they do. I am so sick to receive these messages for the two said unknown numbers indicating they are running out of airtime or data. What a lot of ****!!!!! Vodacom wake up.
