Bought voucher for home wine tasting experience (6 people), plus additional voucher for friends. Arranged date and time for the 6 person wine tasting session, but not had any response or confirmation. Unable to get through to anyone. Calls are answered and then transferred to another number which always goes to voicemail, asking to leave contact details and they will be in touch. After 3 times in as many days, no one has been in touch. This company is a scam! Avoid, and don't make the same mistake as me!
