Vodacom - Poor service as always

I was recently contacted by Vodacom for a upgrade on my cellphone contract. I signed up for the deal that included Data and airtime. When the new contract kicked in, I had no airtime or data. I contacted Vodacom and needless to say, the helpdesk is pathetic. Takes up to 20 minutes to eventually land with someone who is able to assist. Well, after explaining the problem, I was put through to a manager called Debbie Coetzer who supposed to get the failed contract cancelled and organize a new contract. Needless to say, service was as expected. It has been 3 weeks now, that Debbie is not coming back to me. Whenever I phone her to enquire about the status and progress, she is not available. She is not answering any messages or e-mails. I have been without Airtime and Data AND I AM PAYING FOR A NEW CONTRACT.
