Alexander Forbes -*********** staff of NO help

On 29 August 2019 i received an email stating that there is still an unclaimed benefit at Alexander Forbes of my late father. I contacted Alexander Forbes and asked if this was correct so that i could get working on it and gather more information. I received another email from Alexander Forbes with a form attached and was asked to complete it and attach all documents. Once again i responded and said that i am unable to complete something i know nothing off. My father passed away in 2011 and in October 2011 i received his pension payout. Now on the form it says are you claiming pension or provident which i don't know as all i am doing is trying to find out what unclaimed benefit there is. I have received 4 emails from 4 different people and the one is more *********** than the next. No one is of any assistance and i am so frustrated as its been almost 9 days and still no answers. Can someone who know what they are doing and who is willing to do their work PLEASE contact me so that i can get this sorted as this is ridiculous. My dad died 8 years ago and now all of a sudden i receive this information about an unclaimed benefit. I don't want to speak to any call centre agents as they have no idea what they are doing. I need someone who knows exactly what is going on and can resolve with in 24 hours as i am about to immegrate.
