I telephoned their customer services to ask what I was informed was a 'technical' question. I was advised to send a e-mail to their 'technical' department. I did as requested, in fact I have sent 3 e-mails since 9th May, none of which have been replied to. There inaction leads me to consider that their customer service is completely non-existent as the intimation is that they do not 'give a monkeys'.
