Unexplainable deductions

It is with a very heavy heart that I am writing this. I went into the bank on the 18th of March and was offered to upgrade my account to a Premier Fusion account which I accepted. I enquired weather there would be any charges for the delivery of the card and was told no there would be no courier charges because it is a new card. Now I have a R110 courier fee charged to my account last week. This is the 3rd time that between my husband and myself we were told there would be no courier fees but we were charged since about October last year. He received a new card because his had expired and I got a new credit card and then the new card for the changed account. That is R330 that was just charged and we have just left the first 2 but I'm not leaving this again this time. I don't know why this keeps on happening. On my previous complaint I still never received the R69 overdraft fee for April on an account that was supposed to be closed on the 18 of March. Then my husband has a policy that goes of on his credit card and they made a double deduction now on 29 and again on the 30th? Can you please explain to me why there's so many hassles with our unexplainable charges or is this something that happens to every account holder but it mostly just goes unnoticed? This is really not acceptable anymore. We need to stretch every cent and then the bank just takes money like they want.
