Standard Bank has no service standards

Zero stars should be an option. I have been stranded in Canada for 2.5 months without being able to use my credit card (even the new one I paid R400 for) and the people over at Standard Bank are simply ignoring any and all pleas for assistance. I've spent hours on phone calls, sent countless emails and still their response is to visit my nearest Standard Bank branch. How is this even remotely acceptable to treat a paying client like this?! They have completely abandoned me and at this point I don't know what to do anymore.
