Remember when lousy mattresses were the norm in hotels? Then, in the late 1990’s, some hotels started upgrading their mattresses and boasting about them, as a way to stand apart from the competition. (Westin Hotels and Resorts was a pioneer, with its “Heavenly Bed.”) A few years later, good mattresses were the norm.

You know what we need now? A door war. The Haggler wants to see hotels swap out their wretched clangers for quiet doors, and pronto. By all means, give them goofy, trademarked names, like the “Dream Latch” or the “Shhhhh Lock.” The first to take up this challenge will be hailed as a corporate hero in this space.

O.K., on to our letter, which has nothing to do with doors:

Q. I was in South Africa in May and was assaulted by three people in Johannesburg who took my phone and other valuables. The next day, which was May 2, I filed a police report and, when I arrived back in the United States, I closed the account at the first available opportunity, which was May 4.

I’ve had a $39.99-a-month plan with T-Mobile for years. My bill for that month was $25,571.14. I told T-Mobile that I was mugged, and faxed an affidavit of the police report. I got some follow-up calls, but none of the callers knew the history of the case. The departments that were supposed to get back to me never did, and whenever I called T-Mobile to follow up, I was told that the concerned departments would call soon. That did not happen. Now T-Mobile has transferred the bill to a collections agency. Neither T-Mobile nor the agency has disputed my evidence, but they continue to harass me. Can you help? Hasham Mahmood
