I had PetPlan from 2013 when I got my rescue dog until January of this year (2017). I filed one claim in that time, for a reimbursement of $170. Last December they sent a letter saying they had lost their underwriting company and had to switch and that my monthly premiums would be increasing from $56 to $67 (19%), the deductible was increasing from $200 to $500 and the reimbursement level was to be 80% instead of 90%.
Needless to say, I did not renew the policy. They were an expensive option to begin with but these increases were ridiculous. Their service has always been good. Oh well.
