Western Natural Gas Co

I have been a customer for more than 27 years of Western Natural Gas. When I recently had my dad call to ordered gas while he was getting gas for his home, I asked him to also let them know I needed a fill. The guy that came out, Llyod shook my gate to I guess let me know he was here, then filled my tank, placed the bill in my door and left. Later I looked at the bill, it said locked cap. WTH. So I proceed to go to the tank and see that there was a master lock placed on the tank. OK. So I call. This is the first time I was ever treated rudely. I was told, well your dad did not tell us your tank was empty so a pressure check needs to be done on the tank. Question: As a homeowner how the hell am I supposed to know that? Also, when Lloyd was at my home and knew I was there, why did he not come to my door and explain that??? So here I sit with 335.00 worth of gas in my tank I CAN'T use until they come do a pressure check. Oh and by the way, they weren't sure when that would be.
