Bad business policies, terrible customer service and extremely rude.

Contacted JB stamp regarding a leaking connection on a high pressure tank THEY installed 1 year and 2 months prior, I was very clear in that I was under the impression it was a warranty replacement and supplied date and invoice number. They said they would send out a technician, no quotes received and no further communication. The technician came out later that afternoon and replaced the connection pipe. One week later JB stamp called me and asked where they can send the invoice for the pipe and call out, a invoice that I had no idea of how it was and for which I was never even quoted! I told them that they should then come out and install the old pipe again as I did not agree with their business ethics. They came out and where very rude towards my wife which had no knowledge of the situation, telling her that he hears that we " Don't want to pay " I will never use this company again and would never recommend to anyone.
