Discovery disappoints again

Two emails, several sms's and four calls from Discovery Bank. While I talked to an agent at 8.30am, they continue to call and harrass me, then hang up the phone. I tried calling back but again they just cut me off. If you arent going to speak like a decent civil human being stop harrassing me !! Honestly. I have work to do. These are constantly interrupting my work flow and clients.
