Absolutely pathetic customer service

Standard Bank is absolutely Pathetic. I have written and called many times to fix a problem with my account. As I am currently outside of South Africa, reaching an actual human being is impossible! I have spent over R30,000.00 on attempted international phone calls. On the rare occasion when I do get through after paying international rates, and waiting for 20 minutes before being able to speak to a person, that person refuses to give me a direct number to call on in case we get cut off. Well we did get cut off. After another attempt, and waiting a long time before someone answered, the operator told me they would call me back if we got cut off, but still refused to give me a direct number. Well. we did get cut off, and they did not call back! Without exaggerating i have probably sent 30+ email to standard bank support and have yet to receive even 1 email back from them. I recently started reaching out to people via linked In who work at standard bank, including the CEO, and they have not got back to me either. Are there any lawyers out there that will help me sue Standard Bank to recover my costs?
