Refund

I purchased a 3 night stay on 7 August 2015 from the Groupon website after 3 days of back and forth trying to find availbility I alerted Montague Cottage that I would be cancelling the the voucher with Groupon (the cancellation period was 7 days) I then immediately (11 August) called Groupon to cancel and asked to have this refunded. I was given a new ticket number and was told I'd receive an email with in 24 hours to confirm bank details for the refund. On Thursday, 13 August I called Groupon to follow up re: forms and I was told that my voucher had been redeemed. I then forwarded them all correspondence between myself and Montague Cottage re: cancellation. This was not good enough and was told I needed a mail where they acknowledge my cancellation. On Monday, 17 August I called complained that the email trail would suffice and was assured that by Wednesday 19 August this would be settled. Marc at Montague Cottage had in the interim sent a mail stating that the voucher had not been reddemed which I immediately forwarded to Groupon. I am yet to receive any correspondence from Groupon and it will now take a further 5 days once they actually contact me to receive my refund.
