I have seen several occurrences of the plural for the name of an organization of company, but also occurrences of the singular. For example, "Mango Ltd. have just put their new 'mPhone 8' on the market, go buy it now!" (imagine "Mango Ltd." is a famous company that manufactures mobiles phones).
Mango Ltd. have just put their new 'mPhone 8' on the market
Is this sentence correct? or should it be
Mango Ltd. has just put their new 'mPhone 8' on the market
or maybe both are correct?
