I have completed the required number of online surveys provided by http://www.valuedopinions.co.uk/ to earn cash. The website has a policy to redeem the cash earned into a voucher of any desired company. I have asked them to send me 2 vouchers for more than 2 months now. I have mailed them but they don't seem to respond. In-spite of asking them to redeem my vouchers hundreds of time, they have turned deaf ears to my mails. Please do not use the service as I think its a fraud and the company should be shut down as soon as possible.
