No help from Absa while overseas

I went on holiday overseas with my wife end of last year. I have been to Namibia many times and always used my credit card to pay for everything and to draw money. I always provide dates/location for my travels. End of last year I tried to draw money,it failed. I tried every ATM in town from all types of banks.When I contacted ABSA via email to tell them I can't draw money, they assumed I didn't know what I was doing even though I was well aware of the daily limit&costs. Two days before returning to the RSA my credit card stopped working altogether,ABSA only phoned me on the day I was back in the RSA.Today, my credit card still gives the same error on mobile banking terminals at shops&restaurants and still ABSA hasn't told me what is wrong. If I had booked my car on my credit card, I would have missed the plane because I could not have paid the outstanding amount, would have no money to to check into a hotel and would most probably be detained because I could not pay the car rental agency. BEWARE! ABSA doesn't care about its clients, doesn't support them overseas as travellers, rather apply for another credit card at a reliable bank.
