International Call Centre is a Farce!

I have been trying for 4 days to speak to someone in International Transfers about a missing Swift payment. I am either number 7; 10 or 20 in the queue with a waiting time of 10 min, and the result is me putting the phone down after 45 min to an hour with nobody picking up! I have called numerous contact centre numbers and this is the only department that can assist me but they are just not available. So to add to the R275 international service fee I paid for a payment that is nowhere to be found I have also spent close to R500 in airtime calling from Germany to track the payment??? Who mans this call centre when all your other consultants answer within 10 minutes??? Ridiculous and unbelievable customer service!
