Back in 2020 I started to receive reservation emails at my email address which were intended for other Hilton guests not known to me. These were all sent to the email address I registered with Hilton and which I use for all my dealings with them. I reported their misuse of my email address immediately to Hilton's Data Protection Team at the time, and after a long drawn-out exchange of emails they assured me that they had resolved the problem, although they never explained how. Things went quiet until July this year when again I started to receive misdirected emails from Hilton, this time providing upgrade notifications for a number of guests staying at a Hilton property in Beirut Lebanon. I received further such emails in August and September this year. Again I emailed Hilton's Data Protection Team using the address provided in Hilton's data privacy policy. I received an automated acknowledgement promising a response but I got no reply so I chased them a month later and again got no reply. I then took to X and have exchanged 15 frustrating messages with different Hilton agents who take no ownership for resolving this at all. They told me that the problem probably lay with the Beirut Hotel who would contact me within 5-7 business days - they didn't. Then they told me to contact Hilton's Data Protection Team - I explained I already did that numerous times and had received no reply. Then this process was repeated by other agents and it's just going round in circles and driving me crazy. I am very uncomfortable that more than 3 years since the problem was first reported to them Hilton is still using my email address to confirm details of reservations made by strangers (and I guess those guests wouldn't be pleased to know that I had received certain details of their stays either). Hilton's repeated failure to grab this matter and resolve it is unbelievable. Of course every message from Hilton comes with the usual words about how they value me as a Diamond member etc, but those words ring hollow and just add to my frustration when all I want them to do is own the problem and fix it once and for all. I don't know if Hilton monitor these threads but if they do I wish they would deal with this thing so I don't need to waste any more hours on it. And if anyone has ideas for what else I might do to resolve this problem they'd be very welcome. I guess in the end I'll need to report this formally to the UK Data Commissioner on the basis that Hilton has consistently refused to engage meaningfully to fix their mishandling of my personal data. More wasted hours and frustration ahead...
