Terrible Service

<p>I was given a cruise voucher when i signed up on a contract. Its has been 10 months since ive been trying to make a booking. Whenever i call the call centre the person on the other end says they will excelate the issue to the relevant dept and someone will call in 10 days, its been over 300 days and no one calls. Ive made numerous calls and sent emails, something needs to be done about this.</p>
