Discovery Card - EPIC FAIL on Service

I called Discovery Card on the 22nd of Jan 2016 to inform them that I would be traveling to Mauritius and that I would like to activate my card. <br> When attempting to draw cash on 3 seperate occasions to great embarassment the card was declined and I had to borrow cash from a colleague.<br> Upon my return to RSA I was greeted with 3 sms and 3 emails stating that my card had been blocked and that I would need to contact DC on their toll free number.<br> I called them on Tues 26th Jan and related my experience to the call centre agent , the agent was very apologetic but could not provide me with a reason or explanation as to why the card had been declined , the agent then assured me that I would receive a call the following day with a new PIN so that my card could be unlocked. <br> Wed came and went with no call from DC , I then called them on Thurs 28th where another agent again apologised and this time assured me that he would escalate the matter and that I would receive a call first thing Fri morning with a new PIN.<br> Frid morninhg no call and then I called them again twice only to be told that there was an error on their system and that I would have to wait till Mon for a new PIN.<br> UNACCEPTABLE
