Ticketmaster STILL NO JUSTIN BIEBER REFUND!!!!!

After several months, I am still awaiting my refund for Justin Bieber Cape Town venue tickets purchased. Over 3 weeks ago, Ticketmaster sent me an email with a RNN reference number and saying I have been successfully refunded. To date, this money (in excess of R8000) has not been transferred to my account. I have sent repeated enquiries and am told repeatedly that I need to contact my bank as they have done all they would by providing me with the reference number. My bank says they don't even know what the reference number refers to and cannot trace it accordingly. I have received many refunds in a likewise fashion back to my credit card for various online purchases in the past and I have never been instructed by the merchants to contact my bank or conduct my own investigation to receive the payment. As a merchant, Ticketmaster should ensure that I have successfully received my refund and should follow up from start to conclusion of the process. I cannot believe that that I, the consumer, am now responsible to chase up on this, this is simply unacceptable! And after having waited for months and receiving excuse after excuse from Ticketmaster for not being able to effect the refund!
