Canyon State bought Mariposa Propane. A year ago Mariposa sold us 2 new tanks that are now leaking Propane and can't be filled. Canyon State wouldn't help us at all. They wouldn't stand behind the tanks and made no attempt to come look at them or help us repair or replace them despite several calls on my part. Their response was "we have no record of you getting the tanks from Mariposa Propane so we can't help you". I explained that I can't be accountable for their record keeping but that they were absolutely the only company I've ever used and the tanks say Mariposa Propane on them. The tanks are 1 year old and should last much longer. They said they probably slapped that sticker on when they filled them.
We've decided to go with Arizona Propane as they have been professional, helpful and responsive. Look elsewhere for a Propane company! Go with Arizona Propane!
