Extremely capable practice

This is by far the worst attorneys office I have dealt with I wouldn't recommend anyone to ever use their service. I'm not even sure how they are in business?.My grandmother hired them to handle the estate of y great grandma in 2015. I have been trying to purchase a property for 2 years now and have given Gambrel the money for the house, they had me deposit it in the estate and have still not sent me the deed. Each time I call I get another excuse as to why the deed hasn't been sent. The last time I called they said my grandma had to pay her bill before they could release the deed. Then in her billing they try to charge for each time I call or someone else from the family calls to see why it is taking so long. We are not his clients and this is a scam for him to try to bill my grandma If they would do their job we would not have to call. If I weren't related to the previous owner I don't think they could hold up the deed this long I also think this is illegal. I called today and was told the deed was sent out through standard mail. Who sends an important document and doesn't send it certified? I think this is another lie and they haven't sent out the deed but I will give it a few more days.
