Bad Service

Good day on Thursday I went in to Vodacom shop to get my details on my invoice correctly updated as my name and surname was spelled wrong. It was send it to customer care to update taking till yesterday to update only to realize someone *********** only updated my name, surname still spelled wrong. I only want an invoices emailed to me with my correct names is this so difficult and is 48 hours again needed for this???? Not my fault it wasn't corrected the first time. This is urgent for me.
