Dependable Heating & Air

I am writing this post on behalf of my friend. She is building a house and recently used Dependable and Heating & Air. Just today she called them asking for an invoice to help get a refund back on her propane gas and Jane told her «It’s not that big of a deal it’s only $ 300.» My friend responded back by saying «Actually, it’s $ 650 for me and I am just asking you for an invoice.» Jane proceeded to say «FINE!» and then hung up on my friend.
I was witness to all of this, because I was sitting in the same room as my friend when she made this phone call. I think it is simple enough for this business to provide her with an invoice since she just spent over $ 12,0000 with them.
I would not recommend them to anyone being that their customer service is HORRIBLE!
