No Service, No Feedback

<p>I received a phone call from Mondo offering me an upgrade from my 2Gig Data Contract to a 5Gig at a reduced monthly rate to what I am currently paying. On further investigation, I found out that my contract was not upgraded but that a new contract had been added to my Vodacom account. This is not what was discussed between myself and the consultant who called me. I contacted Mondo to discuss the situation with them. They informed me that they were going to do an investigation and listen to the recording of the conversation and get back to me. It took a week and a half for Mondo to send me a text message stating that the investigation has now been completed and for me to call Mondo. I have tried calling Mondo on numerous occasions and get put on hold for hours. I finally sent an email and have still had no feedback. How can this investigation be finalized when no one has had the decency to contact me. I am now highly irritated and will take further action if I do not receive feedback within the next 12 Hours.</p>
