Non-attendence to my insurance claim.

I have have ad car insurance with Hollard Insurance since February 2017 Policy number HOL- ********** . In September 2017 I was offered a better price by Miway with my risk profile and cancelled my insurance with Hollard effective 30 September 2017. Unfortunately a stone hit my windscreen during September and cracked it. I sough to file a claim with the Hollard and experienced the following: 1. The call center agents pretend to be unable to hear you when you try and file a claim. 2. Whenever you get through to the agent they pretend to transfer you to another line which rings to no end alternatively they pretend to transfer you and actually put the phone down. 3. I tried to contact Hollard via Facebook on the 27th of September 2017 they promised to respond to me within a day which they didn't. This I think is because they knew that my cover was expiring at 30 September 2017. They however still liable to pay as the incident happened whilst I was still covered by them.
