Has anyone ever had any dealings with a company called 'Special Branch Tree Service'? According to their card they are based in Bow, but there is no physical address on there and I've googled them and can't find anything. They offer all kinds of tree/hedge services as well as specialising in 'maintenance free gardens'. The contact numbers on the card are 07475 622814 and 0800 191 0406 but I've left endless messages on their answerphone for almost three weeks now with no response. I think I may have been scammed, but wanted to see whether anyone else in the area had any experience of using them.
