Complaint Review: Amerigas Kalamazoo

Our tank was filled on 12/9/2017 and then went to 0% on 1/27/2017-They tried to tell me that this can be normal??  After the nice weather and knowing how conservative I am with our heat and other appliances, I knew better, plus calling their emergency service line they told me they do not do emergencies after 7pm????  We were on 0 and they did not care, period.  I had to ask the twice to come and safety check the tank!!  What is wrong with these people??  I am switching in March as soo as our contract is up!
