Someone came to my house from Simply Home and explain about house protection plan (Plumbing, HVAC) which covers the house and don't need to worry when problem happens in home. as explain, I bought protection plan on March 7th, 2022 and I been told that it's 30$ per month all time. I made pre-authorized so money was deducted automatically and I didn't notice they have increased the price (without any notice) to 47.26$. Now there was a problem in my house for plumbing. I called them and guy came to see problem, he said, we cant see issue until you break the wall. we cant break for you. I shock as I been told that they will take care for all issues. then I though let me take a quote for furnace from their supplier. they gave me 3000$ more price than market value. I decided to call the person who gave me this protection plan but she did not pick the phone. so I called customer support and explain the whole situation. they said we will give her extra session for training but it's not resolving my issue. I told them to cancel my service. Also, I took their email address from their site and wrote an email on Nov 23rd, 2023 for my service cancelation officially. I got the confirmation from their side for cancellation as well. Now they charged me for last two (Dec & Jan) months even though I gave cancel notice. I called and came to know from their billing dept. that they haven't received my formal email for that. I told, I sent email and got the confirmation from their side. so basically their staff did not communicate to their billing department. First she decline to give money back for Dec. month but then she was ready as I was having a proof. They sent me invoice for Thermostat, which they installed in my house. they charged me 598$, I asked them to take it back but they decline. I wrote an email and follow up 6 times for my questions but they did not reply to my any emails. I can provide more updates over the phone as there is a limit of character.
