Not what they advertise on the internet

Why do we have to resort to this forum when we call and ask someone to assist us. I saw a special on Vodacom on line for a contract at R80 per month. I was a bit surprised at the cost and contacted their online chat service and confirmed with the agent that yes it is correct. I then took out the contract and when I checked my online orders it did not appear. I then contacted the chat service again and was advised that the phone I ordered was a different price. I was then told to contact the after sales department. After speaking to 6 agents I spoke to the team leader Thobogo who advised he will look into it and come back to by close of business. I know he has to go to IT to retrieve the online chat but I didn't even get a call back to say this is where we are at. I am without a phone and no one can help. <br> Can someone please assist.
