Appalling service from the Blue lagoon hotel East London

I made a booking for my family to stay at the hotel in December on 17 November 2022. The booking was for the period of 24 December to 30 December 2022. The hotel requested a 50% deposit which I paid on 17 November. Subsequently, I canceled the booking on 15 December due to work commitments and I was informed that I would receive a full refund in 30 days. On 15 January 2023, I wrote an email to the hotel to enquire about my refund as they had not paid me. And there was no response from them. I called the hotel on 18 January to enquire about my refund and the receptionist was obnoxious, very unprofessional and unhelpful. She transferred me to finance and the lady at finance informed me that the money will only be paid on 31 January 2023. I have been very inconvenienced as I need my money urgently. There was not even an apology from the hotel and I'm not even sure if I would even receive my money back. The service was very appalling and unprofessional. I would never make a booking at that hotel ever again. I'm considering undertaking legal action to recover my money from them.
