Bad customer service

Good day I'm writing this email with a heavy heart because I have been waiting for my MTN sim card for over a week now of which I was supposed to have gone to Northern Cape for work purposes of which I did not make it to the interview because of the incompetence of DSV warehouse staff .Today at around 09:30am the driver by the name of Wiseman called me to say my parcel has been mixed up and send to Bloemfontein and my street address is Wietsieshoek street Diepkloof 1864 not Bloemfontein dont.they know how to use maps and google maps before dispatching parcels to drivers.Believe you me I don't blame the poor driver I blame the warehouse staff I'm also working in Logistics so I know this. Please get competent staff so that our parcels don't t get mixed up and train them on google maps.Can I have my Sim card delivered and rectify this mess.I stay in Diepkloof not Bloemfontein.
