Disappointing Service!

I’m highly disappointed in your company’s service! On the 26th of November I took out a data contract for my current number. I asked the salesman for a data deal that I can use in my phone but that I can load airtime on as well and after looking through the deals he found this specific deal of 250gb, 150 Anytime and 100gb Night for me. I asked him twice before my dad signed if he’s sure that I can use this data deal with my cellphone and he assured me that yes I can and said that it’s also possible to load airtime on my phone. He said that I’ll have to just pay an extra R10 to link my number to the contract and then everything will be fine. Since yesterday morning my network has not been working. I cannot receive messages or calls and that’s when I went yesterday to Vodacom at a different branch that was closer to work and the guy told me that the salesman that gave me the contract, gave me the wrong deal and that this specific deal can only be used in a Home Router device and that I should let him reverse my contract. When my dad and I got to the branch that my dad signed at for the contract, the same salesman that helped us before did not want to assist us and someone else assisted us. After 20 minutes of looking at the deal and trying to get the Salesman to explain why he gave this contract to us and not wanting to answer. The lady that helped us as well as the manager told us that it will take a month to reverse the contract and that I won’t be able to use my sim now until January 1st. I was told that I should get a different sim for this month which will be a lot of maintenance for me for just a month since all my personal and work related matters is linked to my current number just for me to change it again after the month period. But now I can’t use my device at all unless I put in the new sim or use WiFi. The contract was supposed to start today. I am being inconvenienced now because of someone else’s negligence and Vodacom not giving proper training to their staff of how their data deals work! I’m going overseas this month for work and I cannot change all my contact details. All I want is for my contract to be reversed so that I can take out the right deal and this problem can be resolved.
