Alta Pest Control review: Pest control not working

I began my service contract with Alta in August of 2021 at 813 Timber Trail in Cedar Park, Texas to service my residence every quarter for $119 per quarter. I soon discovered it was not working as advertised. I called and spoke to a manager and they agreed to send out another tech. I decided that their service was not working as advertised. The next quarter I noticed that I was still having the same problems with ants, spiders, hornets and scorpions. I called to complain again and they suggested another tech. The next quarter I wanted to cancel the service and they suggested that I had 1 more treatment according to the contract. I agreed to 1 more treatment and then I would cancel the service. When the time came to cancel the service they again indicated I had 1 more treatment according to contract. Now they refuse to cancel the contract over 1 year later and have begun to harass and continue to tell me I have 1 more treatment. I have sent emails and called them to cancel and they refuse.
