no serial number on invoices or contract - Consumer Complaint for Vodacom - Head Office

in order for apple to honor the guarantee on a macbook pro they need a serial number reflecting on an invoice or a proof of purchase. the macbook pro is currently on a contract with vodacom and Randall from the call centre promised monday that he will provide me with this but he is either not at work or when at work he dont do his work. and all my efforts to obtain it from the social media portal is in vain.. it seems that randall is the only one working there.
