Treating the customer unfairly

I must say that I was disappointed with the way that outsurance treated me as a customer, I had a life cover with the that I have had for more than 8 years. I have been paying that policy religiously for all these years in 8 i have missed 2 payments which the second time was an error where i accidentally request my bank to reverse a payment the incorrect debit was then reversed and they immediately cancelled my cover and in my understanding of the insurance policy you supposed to would have missed 3 consecutive payments for cover to be cancelled. But lessons learned I will not even consider them in the future.
