Telkom poor service provider

I lost my sim card about a month ago, i tried calling Telkom for a sim swap and the call centre refered me to the service center. I went to the nearest branch @Maponya mall in Soweto, the consultant that assisted me said she did the SIM swap and the card will be active in 48hrs, after 3 days it was still not registered. I went back and they told me I should wait for 24 more hours, the SIM registration still failed. I went back again, I was given attitude and I left without help, I've been there countless times and no one is willing to help me and they are always offline. I'm spending money to go there and I get sent from pillar to post everytime.

I also have a contract that has expired but I'm still getting billed, I went to the same branch to cancel it but was told to do it online but that wasn't helpful. Telkom is reaping me off. I'm very unhappy with the treatment that I'm getting from the service provider and their consultants who careless about the customer.
