Breach of Contract

Im dissapointed with Vodacom service, for not honoring my contract. Im on a package where I receive R200.00 airtime and 1gig data a month, and this month Vodacom only gave me 100mb, while I asked for a high premium of R329,00 to have the 1gig and 200 airtime. I want my 1 gig data to be loaded to my account. On the 24th February 2015, I went to Vodacom in Richards bay, to block my phone that I lost. The shop assistance were busy with other clients, I stood waiting for a shop assistant to assist when there were done. The lady by the name of Zakithi was free, I walked towards her and greeted her, she looked at me I greeted again she shouted Ohoo!! I was terrified with her attitude, when she was asking me which sim card was used in that phone, she was angry I asked her if they was something wrong. Get rid of people who feel they are doing customers a favour if we go to those shops, I dont need their stinking attitude.
