Stranded in USA

I was travelling in USA 1 - 9 April 2015. I informed Bluebean beforehand, and when in USA and I used my card, it stopped working. Card was stopped by Bluebean. I phoned to enquire, card was then reinstated, it then worked for one transaction. The next time I tried to use it, it stopped working, leading to embarrassment. I then phoned, spoke to Byron, who told me that my card was again stopped, due to me phoning to stop the card. I then stated that I had in fact NOT stopped the card. He said he would get someone to investigate and email to me. No one ever emailed me. That same day, I sent approximately 20 emails to both Standard bank and Bluebeans helpdesks. No reply. I was in USA with NO WORKING CREDIT CARD. When I returned home, and enquired from Byron, he said he would ask management to call me. Till today, (21 May 2015), no manager has called.
