Terrible Treatment

Good Morning I am not impressed at all with Dotsure,i am frustrated and disappointed,i feel like I wasted my money and I was taken for a fool,i registered with then this year in May for my cellphone cover,and in August when I lost my phone when i had to claim they told me about things that they never told me they would need when selling me a **** cover,i am very upset,i paid every Month and when I had to claim I was told they need prove of purchase which they didn't tell me of when selling me the insurance,i told them I can't provide that due to the fact that the cellphone was a gift from my ex whom I had no contact with,i was taken up and down,they needed IME number then I called my sister who stays at home in the farms where I don't stay,she misunderstood me and just gave me the IME for the wrong box of phone,i then informed the insurer,they then told me to send the correct one,i did,mind you their communication level have been terrible I always had to ask them about the progress of my claim,now it's been over a month now they sent me an email saying they cant pay because I couldn't produce proof of purchase,which i told them I don't have,i really need a phone and I feel like I was played by this Dotsure,please help
