This company is a scam!

My boyfriend was scam a huge amount of money by this company. They work together with people claiming to work for Eskom, sending request for quotations and then giving out purchase orders. Rotec Engineering (with a 'c' not a 'k') is found online, has a landline number but it diverts to a cellphone number. They take orders telephonically and send you all the paperwork quotes and invoices) via email, then they tell you to send through a deposit for delivery of the ordered items (my boyfriend ordered cutting plates that were to be delivered to Eskom according to the order received). On the said day of delivery, at Eskom he was told that there is no person with that name that works there and when Rotec Engineering kept on saying that the ordered items were at Lanseria airport being offloaded. He requested that the order be cancelled and his money refunded. This happened in October 2017, up until today his money has not been refunded. Please be careful. Apparently this is a scam and small businesses are being targeted.
