A client called on Thursday to talk to someone in the billing department, my associate and I have a separate business that handles all the billing for the commercial as well as residential Heating as well as A/C upgrade as well as maintenance business. I told the client that I would have to check into things at the billing department as well as I would get back to him. I wrote down all of the customer’s information including her name, phone number, as well as the number of the invoice. After I hung up the phone, I right away called the billing department. I waited on hold for 5 minutes before someone entirely answered the phone. I told the woman on the phone that there was an issue with the billing for my commercial as well as residential Heating as well as A/C upgrade as well as maintenance business. It took her a few minutes to find our account. Then it took another minute to find a particular invoice that I was referring to. When the client found the invoice, my associate and I decided to go over the billing as well as that is when I found out that bills were getting mixed up in the office. After the invoices were being sent to the billing department, they were getting mixed up. I told the woman at the billing department that she had to get to the bottom of the issue because I was distraught that more customers were going to call to complain, but she fixed the issue with the invoice that I called about as well as I had three more calls over the next two afternoons about inaccurate bills for our commercial as well as residential customers. It’s hard for our clients to trust the business, when they acquire inaccurate billing.
