Strugling to get claim documents

I have a Reinforced Endowment Policy no AL***X5, that Matured 1/7/21. I have started to phone AVBOB since 7/6/21 to get the claim procedure and forms and till date almost a month later, after 8 phone calls, 2 emails and 1 complaint logged on your site, I am still were I was on 7/6/21. Several empty promises was made to me, that they will phone me back and will send me the claim forms. I really can't understand that a huge brand lile AVBOB is treating their customers like this. How are you not able to provide your customer with claim forms? Worse service I received in years.
