Very disappointed and unhappy paying customer

My car is insured by First for women. I am a single Mom with a toddler so it is very important for me to have a reliable service. I have signed up for car insurance and unlimited tows if my car breaks down. Well yesterday while I was driving I could not get my car into gear and my clutch became completely unresponsive. It could not go into any gear. I had to pull over on the side of the road. I called the call centre continuously only to have every agent tell me the same thing that they cannot hear me, can I please call back and then the call would be ended. It was incredibly frustrating. I then called my Mom who could hear me and she came to where I was stuck and again we tried to phone from her phone and the same thing happened. I did not end up towing my car with first for women and that is an extra service I pay for every month. On Monday I will be cancelling my insurance and I will find another company that can actually respond to me when I am in trouble.
