Bad customer service

A month back a made an order online for Ups Inventor, unfortunately I then informed they out of stock whilst their system showed they do have stock however I then started raising my dissatisfaction with the branch at boksburg they opted to provide me with an alternative product according to them it cost more than I initially paid they were comfortable to proceed as such given inconvenienced caused to me. I was settled at happy with the solution only to find out that upon delivery of the product I was given a rejected product which was not new. It came with only three wheels not packaged properly, no manual. We tried to use tht during loadsheding first time but the Inventors battery was critically low how if it's new should come fully charge. That confirmed my suspicious tht Leroy gave a second product how dare they...we were unable to charge the battery took it bck to the store Anthony from Electric dpt tested product discovered that the fuse is off.. My question was how if it's a new product unfortunately this person was very dismissive he did not show any empathy to my situation nor was he willing to listen to my frustration. Just told they out of stock they will go me my money back..I was shocked with the service I agreed to take money back given nor one was willing to listen. This was on the 2nd Nov till this date still waiting for my funds to be paid bck..I will neva purchase anything from this company bad customer experience..arrogant staff
