It IS Gotouchdown saying I've entered a contest to win a trip to Africa (Discover Africa) and I've won 2 $800 travel vouchers for use on their travel plans. Makes an appointment for them to call you and discuss your options. You MUST be in front of your computer or tablet during the appointment.

Caller: Go touchdown tours

Everyone is a winner, apparently. Monthly winner but advised I must take advantage immediately as it is a first come first serve basis. No website available to check out the details as he said they are a new company.
Caller was rather rude and kept calling me the wrong name.

Number calls and doesn't leave a voicemail. Assuming SPAM telemarketers

I called back the number (07) 3063 0743 and reached vm that said I reached Go Touch Down Travel and Tours

Called back.Pre recorded message for African travel specialists. I hang up before the message played any further
