Terrible customer service

What a horrible experience. I have been a loyal Vodacom customer for such a long time. But they are such liers. The dream they sell with the summer gigs. I was supposed to receive 450MB data but it was never allocated to my no. I called the contact centre 4 times. The 3rd and 4th times I had the displeasure of speaking to 2 gentlemen who clearly were not interested in assisting me. The tone they spoke to me with. The rudeness. I was irate with everything but they were not even interested. The last guy went as far as to tell me he was tired of listening to me and then I must now listen to him. He was the one in charge. As a person who works in the customer services industry I was appalled by this as I know the importance of listening to the client and making sure you make the customer feel at ease. Thank you Vodacom for not teaching your staff the importance of customer centricity.
