A UKASH spokeswoman said Lynn’s £150 code was cashed 20 minutes after she sent it.
“Do not send Ukash to anyone cold-calling you to offer a tax rebate, personal loan or any other inducement. This is a fraud and you will lose your money.
“They may claim to be from the Ministry of Finance or a loan company but in ALL cases they are fraudsters who will ask you to send a fee in the form of a Ukash voucher code.
“Never email vouchers or give voucher codes by email or over the telephone to anyone as you will lose your money.
“Ukash advice is never to provide any voucher details to a third-party by any method as it should be treated just like cash.”
Only spend Ukash online and at genuine merchants listed at www.ukash.com/spend.
