Unable to Cancel

I'm trying to cancel my Vodacom contract because its so incredibly expensive. I would like to keep the current number and go onto prepaid, <br> I am an expat working in Sierra Leone and Vodacom roaming is just not feasible for me financially. I signed up for the accounts website and I try to send the email but nothing happens the button is just dead. Previously the email went through with a promise that I will be contacted within 24 hours.<br> I had a good laugh about that one thanks Vodacom. I do not want to go to the shop in Richards Bay because the ques are so long and the staff treat you like a peasant who is intruding onto their holy ground. I have been an extremely loyal customer with Vodacom since the age of 16, I am now 30. <br> I am so disappointed.
