Endor*****t cancelled for the second time by "mistake"

I have had many issues with Dotsure from inception of my policy, from debit issues, wrong dates, incorrect information, and waiting periods due to their "systems", I have also given many compliments especially when it comes to claims and given credit where credit was due, unfortunately I'm at my wits end, once again I cancelled my service plan and had an endor*****t to upgrade my warranty effective from this month, note that I waited an extended period for the upgrade due to them cancelling the endor*****t once before, this has however occurred once again, I am now being told I will be debited my increased premium but will have to wait for August to claim? and nothing can be done because it's the system, this was clearly not my fault as whoever cancelled my service cancelled my endor*****t, I am in the middle of moving places and have so much going on, I don't even have the time to cancel everything and find another company and there is no solution from Dotsure aside from I need to wait?
