Terrible Old Mutual customer service

I am utterly disgusted and disappointed in the rude service from old mutual. A lady called me now to offer old mutual car insurance. I firstly asked her to call back after 3 as I am at work, she continued to say it will only take 2 minutes of my time. She carried on and I said I do not wNt another insurance as I am happy with my current one. This rude lady just put the phone down. Who ever she is, she needs to find another field of work where she does not deal with customers.. We all have to be kind to one another at the end of the day. She has put me off dealing with old mutual on a whole. Terrible customer service.. The number she Called me on is +***
