Highly irritated client.

I am highly irritated with the service I have been given by vodacom. I have had a contract with them for the past two years and paid it accordingly. Now that the contract has been finished and I have taken a decision not to upgrade, my sim card has been disconnected and I was advised that I need to Rica the sim card. Did I not Rica the sim initially when I took the contract. I tried to go to the two vodacom stores the Durban CBD which are Vodacom West Street and Vodacom Field Street and both stores keep saying they are off line but they are able to assist other people who are taking up contracts. I find this ridiculous and annoying and I feel like I am being punished for not wanting to upgrade the contract. I have been disconnected for the past two days and not able to receive calls or make calls. This is a huge inconvenience to me and feel they should have just said if you no longer want me as your client instead of treating me like this. I have tried to contact vodacom using someone else phone but the voice prompts are so ridiculous you struggle to even get to speak to an agent. I emailed and still no assistance.
