Signed up 2 weeks ago - no communication

Wow, not sure how this company survives in the 21st century. Signed up via the internet 2 weeks ago. Gave all my details including bank details. Not one communication from them. No automated confirmatory email, no calls - nada. I have called them 3 times (one one occasion waiting 20 minutes) and explained that I would still like to go ahead. Still nothing. If this is how they treat new customers not sure how they treat old customers. Stay away.
