Incorrectly Billed

My Father received his usual account from vodacom but in the same envelope was another statement for a person with the same name but from Meyerton. This person had done an upgrade on an IPAD. When my Dad went to the Wonderpark Outlet, he waited in the queue for 45 minutes and then when he got to the front of the queue, the person tried to help him for 5 minutes and then said that she couldn't help him any further because she had other customers. My Dad then phoned customer care and they said that he must go to a police station and make a statement - why must my nearly 70 year old father go through all this when it is not his fault. Vodacom should surely be able to sort this out for him without him having to waste his days in a vodacom shop and in a police station.
