Vitality Mobile - Cell C Call Centre Service

My address on my monthly tax invoice has been wrong since I joined Vitality Mobile in May 2014. I have asked the call centre to change it 3 times, but unfortunately it is still incorrect.<br> <br> Because my cellphone invoice is one of two bills I receive with my address on and the other my bank, I had to get an affidavit for the second time now for documents I had to give to the bank.<br> <br> This is not including the extremely bad service I received from the call centre in May 2014 trying to change over to Vitality - Cell C.
