Can't handle simple instructions

The level of service and intelligence in the call center is appalling . I have what they call an 'open line' contract, which means that once my data runs out I cannot buy more. I called in July to change this so that i can buy data and it was not done. I called again in August, giving Autopage a second chance. The agent i spoke to said that it will be done and even helped me buy a data bundle while I wait for the change to come into effect. Yesterday I get an sms stating that my entire package will change. I was never told that I needed to migrate my package in order for my request to be processed. I want my old contract package back with the option of buying additional data bundles, as agreed with two different call center agents in July and August. When i called in this morning the agent advised that my request can only be made via a migration and when I asked to speak to a manager as this was not told to me last month, she cut the call on me. I have call center experience and I know first hand how inbound calls should be handled and the lack of professionalism and common sense in the Autopage call center makes me question their recruiting and training processes!!!!
