The customer service is bad 👎

This must by far be the worst company I have ever had to deal with ,they so professionally in collecting the premiums but they dont care about their customers needs and the agreement ,my the contract ended in Dec 2023 ,but still expecting me to pay the premium agreed at the end ,so i paid a buyout agreement and i want the confirmation that the item is paid up bought out and that they support to give me the confirmation slip or etc .but no response on it .informed me that I must wait for it.why should I wait for something I paid for?
