Disappointing and Terrible Service for Discovery Platinum Card

I app**** for a Platinum Credit Card on the 8th September online, after which I received various emails requesting me to send them a numerous amount of documents, which I did, then again twice I was asked for documents (some of which I had sent already) and again I had sent them. Finally after 14 days (2 weeks) on the 22nd September I receive my Credit Card which anyone would agree with me that it's a ridiculous period, this is the first encounter of bad service. So their courier company arranges to delivery that credit card between 10a.m. - 12p.m. on Friday the 22nd September, I leave work and wait at home to get it, no one bothers to pitch up and someone calls me and tells me they have to reschedule because the driver had to attend to other client, this is the second encounter of bad service. So I get the card and try to activate it but no, it won't allow me to because they haven't received my documents, so I agree to wait and it's the 26th September, so this useless credit card is of no use because I can't activate it since they still haven't received my documents from the courier company and due to this they can't activate my card. Now I'm sitting with a piece of fancy plastic which I can't do anything with, this is the third encounter of bad service. I called in three times today (26th September), all the consultants told me that they have escalated this and would give me a call back, no one even bothered. Had enough of them and decided to cancel this card. I would suggest everyone to not even bother applying for the their "Credit Cards", it's a waste of time and effort with pathetic and lousy service.
