Standard bank fees

Today I opened my credit card bank statement and was shocked to see I'm now being charged for purchases online overseas at a percentage of 2.5% to 3% per rand. This has never happened before. I will be looking to bank somewhere else. I used to get a good positive balance interest rate and this fell away when I was automatically transferred to the gold credit card from bluebean card. I don't know how they expect there customers to afford these charges they keep loading on my account. Just a pity I have built up such a large overdraft, so am stuck in a rut with this bank. Only time you hear from this bank when they want money. I'm warning others not to go over there credit limit when buying online from overseas and keep a close eye on your balance, do your own sums, don't rely on your balance shown on your statements. Otherwise you will be bombarded with calls from your bank asking for payment. This bank is *********** the customer with there bank fees. What will they think up next, I don't think there is much more. We must pay them to keep our money which they make money from, doesn't make sense does it.
