I signed up with them a few months ago, and have been very happy. However, I received a phonecall half an hour or so ago, from an unknown number, with someone claiming to be with Barclays Merchant Services, who asked for my feedback on the service and for me to confirm my date of birth. I've called Vidahost, who confirm that they do use Barclays as their payment provider. I'm just wondering if anyone else has received a similar call? A little worried that it's a phishing call now 
I've just checked my bank account and there's nothing amiss, but thanks for setting my mind at ease!
