Travelodge Hotels complaint: No sleep

We stayed on the 3rd floor and no sleep for the entire stay,the sound, noise was fron a fan duct inside a cupboard which simply amplified the noise. The whole room was noisy and vibrated, after tge first night of no sleep, I spoke the the reception about swapping our room,trying to investigate the noise,accompany to my room to hear the noise fir himself the answer to all of these was no.

The second night of no sleep was unbearable, we even comptemplating sleeping in our car he noise was that bad, the next morning, another member of staff asked us I’d we’d had a goods night sleep, we explained what had gone on, she then offered us a full refund although it would have to be in vouchers, it’d take a maximum of 28 days to process the refund, after 28 days no email or contact from travelodge, I emailed them no reply,I put in formal complaints using thier template no reply even though they claim to respond within 48 hours,I’ve tried calling them I can’t get through.

I’ve tried calling Cameron toll and ask to speak to the manager, they’re never there, I’ve got videos of the noise,unfortunately I can’t attach them I’ve tried but they’re too large, after I got home I we on TripAdvisor and there’s loads of similar complaints all from people who stayed on the 3rd floor apt310 or there about
