Terrible Service from Standard Bank Insurance

It's been 11 days that I am without a geyser. I am told that the manufacturer does not have stock. The geyser is under warranty. Standard Bank insurance has continuously failed to make contact with me. I am keep being promised they the manufacturer will contact me, still waiting since the 18th of March. The team leader, Ikram is returning my call since last week Friday. His manager Tebogo is returning my call since Monday. I have not even had a reply from the CEO Shakeel Ebrahim. I lodged a complaint and that departments turn around time is 8 days. This complaint was logged last week Tuesday. I have had a death in my immediate family and had to prepare and host 2 prayers with no hot water. I have 2 little kids. There is no fairness to the customer in this situation. There is no care and understanding. Standard Bank has really made my bad situation even worse. How do I get compensated for this unjustly treatment from such a major company that doesn't have stock for almost 2 weeks. Which is not my problem but theirs. Need someone to make things happen. How nice if the customer can say I don't have stock of money to make your installment. Standard Bank, will you wait for 2 weeks for your payment? Disgusted
