Pathetic service

I have been trying to purchase one of Vodacom's online data deals for over a month now. I have received confirmation emails, however, when i called to follow up i was advised there was an error on the system which will have to be dealt with by another department and i will be called back. My calls are never returned and when i call, i wait on the line for close to an hour, only to be given a different story each time. I have made numerous requests online to be called back. I have only received one call back. That call cut and the agent did not call back. Vodacom's agents are rude and ***********. Their customer service is absolutely pathetic.
