Why is my bill different this month?

A bill that moves without warning is worth a call. Before you phone, here are the usual reasons from the agreement, so you can find the line that changed.

What are the usual reasons?

The first invoice includes the prorated charge for the rest of the current month plus the installation charge and any materials purchased (Section 2). That makes it different from every later invoice. If you changed plans mid-month, the same proration idea applies, though the company has not published how it handles a change, so ask.

Overage is the next one. Each plan has a data transfer limit, and use above it brings a surcharge of $1 per gigabyte over the limit in the billing cycle (Section 1). A month with big downloads, backups or game updates can show up this way. See why data use jumped this month.

What about visits and taxes?

A visit where no fault is found, where the trouble is in equipment the agreement does not cover or where the technician could not get in is billed at current time and material rates (Section 12). Taxes are added "if applicable" (Section 2.A), and no tax amount is published.

Late handling matters too: invoices are past due 20 days after they arrive, and the company says late payments must be approved or services can be forfeited. No late fee amount is published.

How do I find the change?

Put the last two invoices side by side and look at each line. The guide on how billing works and the article read your bill name the lines. If one is still unclear, call 775-575-9593 and read it out. Questions about the agreement itself go in writing to billing@hdiss.net.

Ask for the reason in writing if the answer is not what you expected, and note the date of the call.
