HOW CAN A REPAIR COST MORE THAN THE WHOLE PRODUCT

This morning I went to Dion Wired in Cresta to enquire about repairing of my tablets screen. <br> I got asked very abruptly where i had purchased the product which clearly is on the receipt and who would take a product that you bought elsewhere to a different store. The cashier too the tablet to the manager returning with the statement. You best get this fixed yourself as if we send it in to get fixed it will cost R2000 just for a screen. I paid a total of R1500 for the tablet. When I purchased the tablet I asked how difficult it would be to repair the screen with regards to cost as well as duration. the salesman assured me it was a good buy as such issues will be resolved effortlessly. I was originally to purchase a galaxy tab but decided to take salesmans advice. <br> <br> My question how can you sell a product to customers knowing there will be no customer service or support. The store could not even tell me where I can find a person to repair it.
