DISCOVERY BANK. - Uncontactable by phone!

Terrible experience so far. Discovery Bank refused a transfer between my own accounts on suspicion of ***** and advised me to contact their ***** line. The thing is they NEVER ANSWER the phone. I am overseas and I cannot wait forever listening to their inane recording while I pay for the call that they don't answer. I cannot pay myself from my Discovery Bank account to my FNB bank account. When I complained on Facebook Messenger, they were quick to respond, but with empty promises of getting their team to look into it. UNACCEPTABLE. Also Ralylen Tekana from Complaints sent me an email promising to look into this, and then deathly silence. Shocking service Discovery Bank!!
