Debit card stopped working while abroad. Sluggish response from Standard Bank

The customer service is terrible! I was stuck abroad and my card just stopped working at all MasterCard point of sale facilities, after setting my travel dates in the Standard Bank app. After being referred to 4 different departments via email, I tried phoning in to the Customer Care. This turned out to be a fruitless activity as they only realized they couldn't help me after sending me to 4 other departments and then concluding that I go to a Standard Bank branch for assistance. The branch also couldn't help me, and opened an investigation. Three weeks later, I am still waiting for a response from Standard Bank and I am not sure what more to do. Disappointing
