Unnecessary bank renewal charges

I was notified by captec bank to renew my bank card for an fee of R55. I responded to say that I won't pay as I didn't lose my card. That is capitec'a policy for charging only to receive a new card. They responded to my emails and refuse to accept my complaint. I am very unhappy with their services as they told me that other banks charges a monthly fee charges. I then told them I'll lay a complaint. A colleage of mine was cotacted by capitec call centre and was told that they will not charge her after she explained her situation and she too denied to pay. Unfortunately i am currently unemployd and has bin a loyal client and can't afford the R55 fee.
