the technician came to fix my Whirlpool Duet dryer. On the phone I gave the operator the error codes I found on my machine. I also showed Andres the technician these codes when he arrived. He spent 2 hours at my house with no success. He wanted me to pay for his time when he did not fix the dryer and wasn't sure what was wrong! I said I will pay when you fix it. He left after arguing and sent me an invoice. The accounts manager called and demanded payment and was very rude. I paid because she threatened to send a collection agency.
