No response after more than a month

I have sent numerous mails the last month and a half about incorrect fees on my credit card. Went into absa branch as well where they confirmed that i am paying for a garage card which i do not have and that i need to call credit card division. I again sent mail after mail after mail with no luck. I get a response asking me for my details and contact nr, which i then supply and then never any word further. Most pathetic service ever from a financial institution.
