Bad customer service

Today I am appalled by Vodacom's service. I had a vodacom contract in the past and I app**** for a new one more than a week ago. That same day I sent through my documents and the person who assisted me asured that I would receive feedback that same week. After numerous emails he phones and says they are busy processing my application. After numerous emails again he phones to confirm that he is unable to upload my documents to the department that has to process them but he a colleague will assist. Today, a week and a half later he phones and states that my application was not successful, when I asked why he could not give me an answer. How is this possible that someone whom has had a contract with them is not accepted for a new contract. I will be moving to a new service provider as soon as possible. Vodacom, please ensure that your clients are helped more productively in the future.
