Service Fee charged for cancelled garage card

Recently, I have noticed that I am being charged 2 amounts for service fee. I then contacted the Customer Services department on 27 November 2019, and spoke to Sifizo. I was informed by her that the charges are for my credit card and garage card. My garage card was cancelled in 2013. I then checked some of my old statements and I see as from August 2016 I have been charged service fee for my cancelled garage card. I have now been refunded the service fee for the past 6 (six) months, however this is NOT acceptable. I have been charged for over 3 (three) years for a garage card that was cancelled in 2013. I want a full refund dating back to August 2016.
