Horrible service

I went to Vodacom in Greenacers and wanted to pay my account and also to get help of my router I miss placed and called in and blocked it. First no queue directions and when I got help from this lady she made me stand, but made the payment, I explained my situation of my router and that I found it now I want to know what can I do should I buy a new sim or just open the old SIM card. She advised me to buy a new sim,she said it could not be done. I called customer care and they explained me otherwise. I want to know why she **** and wanted to make money out of me. This is Robert store I think it’s a franchise store. I still want to port my sim to CellC because horrible service. And I went to Vodacom head office in cape road in Port Elizabeth which they turned me away. Security said if you don’t know anyone inside then you can’t enter. So tell me why should I still be at Vodacom. My name Rossy Brown ***
