Shocking Service when trying to cancel a policy.

SHOCKING SYSTEM, SHOCKING SERVICE ROVIDER. I took out pet insurance for my pet a year ago with One Plan Pet Insurance. They were only too helpful when I app**** to take the policy out. Ha! hA! try cancelling the policy......not only do you have to send them an e mail requesting cancellation but you cannot talk to anyone in the Retentions Dept by phone call. You simply get told they will call you. Well.......over 5 days now and not a single phone call, not one. I did however receive another copy of the Original Policy via e-mail yesterday. What a joke. On phoning them again today, told the same thing, they will contact me. Oh well ....... still waiting, yet again.
