For anyone in the UK who has seen the PDF document from GTL will know that a prepaid account can be set up using money transfer via Western Union so calls can be made to the UK. This is not the case money can not be sent to GTL via Western Union as money can oinly be sent from the UK to a person not a company.
As per normal with Western Union they are no help at all in trying to solve this problemm and you will be lucky if they respond to any questions at all, myself I will not use them anyway due to past experiance. If you want to receive calls from your pp/loved one in the USA look for another means of doing so. Gtl are also no help I have had email deleted with out being opened so no hope of help from them.
