I sold property 1911 N Bison Ridge Trail, Show Low, AZ 85901-29045, with close of escrow 05-16-23. I called AmeriGas (928)537-4944 and cancelled service effective for close of escrow date as previously stated. Account # is 204082790. On 05/28/23 I paid what I thought was final bill for this account, amount paid was $23.03 (invoice #3150877627. Early June I received invoice #3151319783 for $154.99 for what looked like charges associated with establishing account by new owners of this property. On 06-07-23 I called Amerigas and spoke with Peng who said he would remove this charge from my name....when I checked a few days later, it still listed as my debt to pay; I called a second time on 06-13-23, I spoke with Ben who told me was in process and it would be cleared with 72 hrs. When next I checked on 06/16/23, balance was $0.00. Then low and behold in November I received a new bill in my name for $199.60, invoice # 3157352233. I called 11/21/23 and spoke with a Mia who told me the acct was still in my name; she referred me to sales; Val in sales said I needed to talk with a supervisor. I was disconnected 3 times trying to speak with a supervisor over a 30 minute time period. I have subsequently talked with someone higher up x2 and have still gotten no resolution to the issue. My last conversation was 12/18/23 (Confirm#: RICM1634018) when I was told that it would be rebilled to the new owners and that landlord account (2477916) would be closed. Apparently I was being billed as landlord of property, but I sold property in May of this ear. So, as of today, the account is still in my name, despite closing it in May of 2023, and I now show a past due balance, which is not mine to pay. HELP! I have reached the end of my rope! I have tried to handle this responsively and responsibly but it has gotten no resolution to the problem.
