Absolutely appalling service on the last occasion....

Absolutely appalling service on the last occasion. I have used hoppa for years and generally find them to be cheap and reliable. However, on our arrival to Zante last month we received no prior communication and no transport was waiting for us. I had to phone up and then wait for a call back, only to be told nobody was coming and to get a taxi. As if this wasn't bad enough, over three weeks later hoppa still have not refunded me and are simply ignoring my emails!!!
