Unprofessional Service

I switched to Vodacom from another service provider. I thought that I would get a much better service. All I got was a number that was incorrectly put on a contract (which means that the service assistant did not listen) and I got rude and unprofessional persons to deal with as well as a manager that mocked my husband because he did not stand in the queue here area, but there was no queue to stand in. This manager mocked my husband and did not realise we came back to the shop. He was busy giving the customers and staff a demonstration on how he showed my husband where to stand and then everybody laughed and he said that my husband was a stupid man. I want action to be taken against Gert Maass as he is giving Vodacom a very bad name. I will be sending my full letter to the complaints department at Vodacom and I would like a written apology.
