Cannot cancel account

I was in Durban to cancel my account, where I was told that I would be able to cancel account within 24 hours if I just do it in-store. I was told that I can do it online, but it would be a month's notice. So now I am on holiday in Cape Town and came in-store to cancel, where I was told that I can not only NOT cancel the account immediately, but not cancel any account in-store! How can one not cancel an account in-store? Very frustrated with being told one thing in Durban, and another in Cape Town. I am not interested in creating an online Telkom account. I just want to cancel my account immediately like I was told I would be able to do! I just want to get rid of all Telkom products in my name.
