Lin-Gas

Lin Gas refused to pick up the propane tank in my backyard despite numerous requests.
I have contacted Lingas first in November 2017 (phone call) to ask them to remove their propane tank from my backyard because I was moving out of the house to another state and that because my house is for sale and that no one will be living in the house it is not safe to have the gas tank in my backyard. My request was ignored. I called again in early December to make the same request. Again it was ignored. In January 2018 I emailed the Lingas company (this time in writing) to remove the tank once again. And again Lingas ignored my request and refused to even reply to my email, nor was there any phone call from Lingas. Today is January 22 and I have been patiently waiting all this time but still no word from Lingas as to when they will pick up the tank from my backyard. Needless to say it is not safe to have this tank which still contains a large volume of gas in the backyard of a house that no one living in surrounding by other neighboring houses. I hope Lingas will pick up their tank immediately.
