Having ordered what seemed to be a good offer on wine from an online deals site, Tom Bailey got back from holidays to be told that the Revenue Commissioners had seized his wine.
"[Groupon] said, well, you wouldn't be entitled to a refund, because the goods have been dispatched. But I said, look, I'm still out of pocket."
Eventually, after much toing and froing, Groupon said they'd replace the case of wine. That was in August. Tom's wine glasses are still waiting.
Paul Lavin also got in touch with Liveline to sound a warning to consumers. He lives in the US and recently travelled to Ireland, having booked his car hire online with a car hire firm before he left. He had hired a car for four days for around €100. The surprises started when he went to pick up the car at the airport.
"All in all, there was €400 on top of the original €100 at the airport."
There was more to come, however. Paul travelled to his destination and then discovered the car had a puncture. He changed the wheel, got in touch with the car hire firm and asked them what the procedure was with a puncture and roadside assistance.
"They advised me at the time that the insurance didn't cover tyres."
This despite the fact that Paul had been sold optional insurance for €200 at the airport desk. He was told that he would be liable for a new tyre if he didn't get it repaired. So that's exactly what he did. When he dropped the car off though, the woman at the desk said he'd have to pay for a new tyre. Paul's flight was in two hours.
"I didn't really have much time to argue with them. I was obviously furious at the time."
The cost of the replacement tyre? A whopping €265. Paul's advice to people hiring a car? Read the small print.
(Liveline got in touch with the car hire company and they agreed to reimburse the cost of the tyre.)
