misinformed about cost

I wanted to move a couple of boxes to Germany from South Africa and got a quote from Seven Seas online. As it was a lot cheaper than the other shipment companies, I worried there was a catch or hidden additional costs, so I logged a Query. I was contacted by someone from Seven Seas on the 2nd of November (a UK number.) and spoke to someone called Kathryn. I asked about the cost and raised my concern about the hidden cost, and specifically ask if there would be custom charges in Germany. The things I want to ship is not very valuable, so I had to weight you the cost. Kathryn assured me there are no extra cost, asp because I don't live to far from their offices in Kempton park, so I paid the R900 deposit. It was only then that I saw a 300 something Euro charge, and mention on Vat when I saw the custom forms. I called the call center, but was barely able to hear what the person on the line was saying. I think there is something with their line. I complained and insisted on getting a refund of my deposit, as I was misinformed and this is exactly what I didn't want. And now I have to wait 10 working days before they will refund me my deposit.
