upset with Standard Bank insurance

I have called standard bank everyday for 3 weeks so I can get my car insurance documents and have the insurance go off on time at the end of March. Every time I have called the contact centre I have been on hold for no less than 5min with no assistance at all. I have sent them emails on the ********** yet I have not received even an acknowledgement of this communication. whats worse is then me as the client are going to be blamed for the premium not going off, even worse than that is my car wont be insured. it is ridiculous that such a big business doesn't take its service delivery seriously.
