Telkom Mobile are **********

I have been trying to close my mobile account and port my mymber to another provider as I have not been happy with telkom. If I try call any telkom number I get passed around from automated msg to automated msg. I requested the cancellation on the app which didn't work either. I eventually went in to the branch to have it done. Now I am trying to port the number and it just will not go through... this morning the SIM died and my new SIM from the other provider was working. 3 hours later my new SIM dies and my number is now working back on the telkom SIM!!! How is this even possible???? I have been at this for a week now.
