Sneaky charges and no response

I saw i had been charged fees on my card which i was not made aware about when i enquired i was told 'o its the new fee which is charged now'. I have since asked Absa to cancel my card i was sent a settlement letter which i paid and emailed proof of payment weeks ago.im still waiting to hear back from them as they are supposed to cancel my card!!!! I want nothing to do with absa after years of support this is how i get treated
