Quoted price differ from price paid

<p>I got a quote for s**** alluminium and s**** batteries but the price paid to me was approximately half of the quoted price. Frane S**** Metals admitted the mistake and offer to pay me the difference in cash, However, I gave them my banking details but they refuse to pay into my bank account.</p> <p>I am far away and even if the amount is insignificant I want it into my bank account</p>
