Paying unreasonable service calls

I used the automated service system to request service call for faucet and stoppage repair in bathtub. AHS reported only the faucets to be repaired because  unbeknownst to me the system only reported 1 problem. I found out that the stoppage was not reported because the automated system can not report but only 1 repair. This I found out when the service repair person arrived at the house. Me, the customer did not know that because the automated system does not warn you about that ahead of time. I called AHS and they admitted to all of the complaints they have had in the past  with the system and they would not add the stoppage repair in the service order even though the plumber was still in my house. They told me that I had to request another service call for the stoppage and pay the $75 service fee again and take another day off from work to have it fixed. They would not waive any fee and pretty much told me it was my mistake I should have called to make sure. The automated system is broken and it had caused me to make 2 separate service calls and pay double. This is not fair. The automated system should allow the customer to request multiple issues or warn that only 1 request for same category can be placed. Now what customer service is suggesting that I call to make my appointments in the future and that means having a wait time from 20 to 30 min. I was not offered any compensation for the confusion nor did the supervisor say they were going to have the automated system work better for the customers. I will never recommend AHS to anyone.
