Simply Pathetic

I had my cellphone ****** earlier this year and advised cell c. They instructed me to buy new simcards and call in to do a Sim swap which I did. They loaded the incorrect number on the simcards and advised me to buy another one to load the correct contract. I now call in to correct their mistake albeit 2 months later now I'm told they cannot do the simswap over the phone beacuse the number hasn't been used in more than 60 days. How would it be used if Cell C loaded the wrong number and made a mistake. Now they expect me to go to a store and pay R150 for a mistake they made. It's not hard to believe that they are R9 billion in debt. Pathetic customet service and after 15 years of being a loyal client I'm finished with Cell C.
