We buy cars poor service lack of communication

I purchased a vehicle from we buy cars in December 2025 , and since the purchase ive had on going issues with we buy cars no email response , customer care agents putting the call down on me mid conversation as well as ignoring my calls, absolutely pathetic , papers for the vehicle took till the end of February to get due to road worth expired , papers were just sitting at the licenseing department forgotten, 3 months later finally received all my papers with not even an apology , to have the car 10 weeks later wheeling and whole unit dismounting from the car due to poor work on the vehicle, ive now been sitting with no car for 5 weeks with 13 calls later no conclusion to what is happening with the car no answers no response, absolutely pathetic is this how they treat their clients? No one is responding to my emails How can I escalate this matter future any phone numbers and emails? Please help
