poor service and lies

my contract expired end May 2020. we called to cancel. From my knowledge if u cancel the contact the sim becomes prepaid or pay as u go whatever it is call. However the agent on the phone said we will have to go into a telkom store as the sim will not work. i was confused but thought it might be new. went to telkom, i was told the consultant "****" to me and my cell number was cancelled. That is very poor customer service, now i need to buy a new sim and get a new number and do all the Admin that comes with changing a cell number. due to their incompetence ive been put in a position that no one wants.

Telkom is very poor and i will never advise anyone to join them.
