Discover bank most disgusting bank and credit card

discovery bank..... disputes. I ordered shoes from Amazon , waited since May, to get this sorted, got an e mail from Amazon that the refund was done. A lady Boitumelo, promised to call me after 15 days, that's when she can do something about it, so that i can get my refund back. since then I haven't heard from her, i send mail to disputes, i have to wait another month. think this is unbelievable, and frustrating. i spend a little fortune every month on my so called diamond or whatever card, pay every end of month the balance and this is how i get treated. The courier picked it up about 3 weeks ago, I have got no money back. so much for DISCOVERY...... disgusting impersonal bank ....
