Here it is:
Thank you for contacting Cineworld.
I would like to offer my apologies for the poor sounding issue which lessened your viewing experience at Luton Cineworld. It is very disappointing on our end to hear of any poor sounding concerns. Although we do have routine sound quality checks on a very regular basis, it is difficult to become aware of the sound issue as it happens due to its unexpected nature.
All feedback we receive here at Cineworld Customer Services is handled with great importance, especially with regards to our customers' viewing experience. The issues you have raised have been reiterated with our manager at Luton Cineworld in order for the appropriate sound and technical checks to be immediately arranged.
I would like to thank-you for emailing us with your concerns. As mentioned, your feedback has been taken onboard and actioned accordingly.
I do hope that this disappointing experience has not weakened your view of your local Cineworld Cinema, and your next outing at Cineworld will meet our expectations of a familiar enjoyable experience.
Kind regards,
Kamil
Cineworld Customer Services
Just as a brief, the issue I had with them and the reason for my complaint was because I went to see Peter Rabbit with my DS, and the sound kept on cutting in and out!
I did alert a member of staff but nothing was done
