Disastrous stay

We booked a romantic night away for our anniversary and my husband's birthday. We paid extra for a classic executive suite instead of a deluxe or a superior deluxe room so that we knew we would stay in a very nice room. What a disappointment! There is absolutely no soundproofing measures between the rooms. We could hear every single word from our neighbors while they were talking at a normal volume, but unfortunately they didn't keep to a normal volume. They had a bunch of drinks, got very loud, put their television on the loudest possible setting and promptly passed out, leaving the tv on until after 3am the next morning. We sent numerous complaints and the hotel simply said they tried to phone them but there was no answer. Of course they won't answer if they are passed out. I didn't hear them trying to knock at any point throughout the night. I sent them an email on the following Monday. They didn't respond for 2 weeks and when they finally did (only after I sent another email) it was to say sorry about the loud guests and to offer me a massage at the spa. 1. The night in question was cold and windy, so I can only assume it was too much trouble for the night staff to offer moving us. I was so desperate for some sleep I would slept in a tent without complaint. The hotel was very far from fully booked, so to move us would have been easy. 2. To offer me a massage is an insult. We were there as a couple, so why am I the only one being offered anything? I didn't expect anything for free, so I declined their offer, but what gets me the absolute most is the fact that they have apologised for the noisy neighbours, but they don't address the actual issue. 3. Why is there no soundproofing between their very expensive suites? I am not supposed to hear a normal conversation from next door. We have stayed there many times before in other room types, but I am afraid this was the last time, which is a pity. It is a spectacular setting and has so much potential. When I declined their massage I asked why they didn't address the actual soundproofing issue. It has been another two weeks and I still have no response. The whole hotel is feeling a bit rundown and tired, but I gave them the benefit of the doubt. I understand due to Covid and the lack of guests there would be a severe financial impact, but Covid can't be blamed for such bad client service.
