misleading information on upgrades

<p> I was on a weekender since 1998 and towards june of 2015 i was reminded to upgrade and i went to vodaworld .I was advised to take a Smart L package which according to them i will save .My bill is around R800.00 and does not change .The idea was that i can cancel anytime but no details were provided on when exactly can one cancel and how the cancellation will affect me.I then called the customer service since i felt that i was paying a lot and not enjoying the contract anymore.Their data get depleted so sooner that i get a pop up message that my data is finished .The lady in cancellations who was trying to assist me this based on what she kept on repeating that when i took the contract they were using the old system and that they are now on a new system and that she cannot access my account .That was on 15/09/2016 and she promised to call back on 16/09/2016.I am still waiting for that call and i am still and hopefully will keep on paying through my nose for basically nothing .My bill shows that i do not use my phone exesively .I want to cancel as of yesterday</p>
