No response to query after numerous emails sent

Sent an email query, which was forwarded to a consultant the following day. The consultant requested my number which I emailed back. Nearly 3 hours later did bit receive any call. Phoned in myself only to be told the consultant is not in and us working from home. Was asked to leave a message which I did. Sent another email and still no response.Forwarded the email to customer care, still did not receive any response by COB.Quite disappointed as if they treat their potential clients this way, how do they treat their actual paying clients???Doubtful that I will be having any further dealings with CTU in future.
