voucher will expire in June and no one is replying

Hi <br> <br> I have been trying to call your office for the past two weeks, I've been getting Voice mails or the phone would ring and it gets dropped. To me that's just bull <br> s%$#, for such a company. My voucher number is A223746 and will expiring on the 30th June 2015, I would like to make a travel booking and you are not helping. I sent emails [Email Removed] - [Email Removed] and up to date still no reply.. that's just nonsense .. I called *** and this number doesn't exists but it's on my voucher .. I also used *** number on your website and whoever uses it ends my calls or it's on to VM.<br> <br> I want a reply immediately on *** - *** because this is not how you treat clients and should I not find a reply to this s#@% service I will take this to another level.<br>
