Discovery Bank Rewards

Very bad customer service. I signed up at the beginning of December 2020 and have been having issues so far every single month. I probably called in about 24 times already spend countless times on the phone and being transfer from one person to the next. When you call in to follow up on your inquiry reference number it always gets escalated but never resolved. The app also doesn't work properly the discounts it's saying you are getting is not the same as what they are paying me back in discovery miles.
