GSM take your money and don't deliver the service... stay well clear of them. They annoyingly send you emails every time a new member of staff takes over the accounts, introducing themselves, asking it they can assist in anyway, only to ignore your reply! I have emailed them in excess of 10 times and received no reply! I stupidly gave them a second chance to get things right to only have the exact same experience again. This is an unprofessional business with no staff consistency. I've been waiting for a refund for 10 months so this is why I've finally written this review! DO NOT USE!
