Bad customer service on over changed item

<p>I bought a duvet inner at Mr Price Home - Greenstone. The price tag and the shelf price was R899. When I arrived home, the duvet was charged at R999. I went back to the closed Mr Price Home at Cresta with the price tag and slip. They said they cannot assist me, I need to go back to Greenstone. This to me is a waste of time, money and petrol . I cannot understand why customer service at any branch of such a big chain store cannot assist me with my problem. I still need to take the time and petrol to drive to Greenstone to get the issue resolved! What a wait of time and money!</p>
