Zavvi has allegedly threatened to pursue legal action against customers who were accidentally sent a PlayStation Vita instead of a copy of Tearaway, according to a letter that's surfaced online.
Last month, a blunder by the online retailer saw an unknown number of customers sent the £169.99 console rather than the £19.99 game they had ordered.
But according to the letter (posted by darkzero.co.uk), Zavvi warned that should customers fail to arrange for the item to be returned, it reserved "the right to enforce any and/or all legal remedies available".
"We have tried to contact you on numerous occasions to give you the opportunity to return this item to us (at our cost and at no inconvenience to yourself), but to date you have refused to do so," reads the letter.
"This is our final notice to politely remind you that you did not order, or pay for, a PS Vita and if you fail to contact us by 5pm (UK time) on 10 December 2013 to arrange a convenient time for the PS Vita to be collected we reserve the right to enforce any and/or all legal remedies available to us."
The retailer also apologised for the "technical error" and for "any inconvenience" caused.
VideoGamer.com has contacted Zavvi and parent company The Hut for comment and to ask why it believes the threat of legal action is the correct course of action against its customers.
