If what you're looking for is to blackmail in order to get a refund, as is already known, you're not going to get it.
. I wish we could comment on you too because we have many things to Say. Another thing, our driver was not coughing or unwell; You are also lying
It's you we don't understand. It's a private tour. Ask how much a van for 7-8 hours from Malaga to Gibraltar round trip costs. Ask how much an 8-passenger van in Gibraltar (UK) with a private guide for 2 and a half hours, including entrance fees, costs. I'll give you a hint, now ask how much it costs, then ask how much the commission is for the Viator platform.
You are the one who wanted to walk from the center to the borders, always after the free time we offer customers to either walk (15 min, with good places for pictures) or take a taxi, which we cover the cost for. Spanish transport cars are not allowed to enter UK Gibraltar by law.
What you should do is take a shared group tour; it will be cheaper for you. I won't argue about the quality of our guides because we are confident that our customers are with the best, and our goal is to provide the best. Know that your comment will give us more energy to work, and you won't demoralize us. I wish we could comment on you too because we have many things to Say.
