Discovery Bank Poor Service

i recently joined Discovery bank and vitality and got an iPhone via the benefit. i met some of my goals over the past few weeks. on the week ending 2nd December i did meet my money goals but it did not show up on my iPhone benefit page. i called the call centre to find out if it can be updated. i called over two weeks ago but till today it has not been updated. i made several calls but to my frustration i've been sent all over and still not sorted. i spoke to a lady called Courtney yesterday and asked to speak to her manager, she transferred me to her colleague not her manager. both she and her manager did not listen to my requests or statements properly. clearly the call centre agents do not hear requests clearly. quite dissapointing service from Discovery Bank which is supposed to be a premium bank. unfortunately not a premium service.
