New name and dodgy story

Hello everyone. I couldn't get hold of the company to do my 1st yearly maintenance, and after discovering that everything regarding the company had been removed or stopped on FB , websites , even google and telephone numbers , I drove to the store to check. To my shock there was still a jewelry store and the same people work there . But it has a new name... Kosta Jewellers . According to them the old owner disappeared back to italy and closed all the accounts and made off with money . I suspect that they ran an " exit scam". The people also told me that this is a new company and has no connection to GC manufacturing so all previous contracts like yeary maintenance are null and they do not do it any more . They also said the fact that the new name is "Kosta jewellers" is just coincidence to the fact that the previous owner's surname was Costa.... I am very wary of trusting the new Kosta jewellers because on their new website there is a statement saying that "Kosta Jewellers was launched in January 2020 as part of a rebrand of thediamondring.co.za" so I suspect that they are lying
