Bad customer service

I purchased a netis range extender for a client from computer mania in kenilworth center which i used but kept ****ing my internet speed after about a week of testing and phoning telkom to diagnose the problem i came to the conclusion that the range extender was faulty I returned the range extender to computer mania and the receipt said 10 day return warranty so on day 8 I returned it unfortunately I misplaced the packaging and was told over the phone by a consultant that i will have to pay a 10% handling fee which i was happy to pay but arriving at the store i was told that the range extender must go for repairs as they cannot refund me if i dont have the original packaging which will take about three weeks i had them send it away and bought a different type of range extender for my client and solved her problem.

After about two weeks i get a call from computer mania saying that my range extender had been swopped out due to the original one being faulty out of the box i then get the new one and the box is sealed so i ask the consultant if I cannot get a refund as i had no satisfaction of using the range extender and i brought it back before the 10 day period and waited on a unit to be repaired which i did not break but was an out of box failure.

I am them simply told no you cannot get a refund and the consultant tells me you must go look for a buyer yourself

I will never purchase anything from computer mania again
