Charged for 2 mobile router as opposed to one mobile router

I ordered for a Mobile router under my business, then two mobile router were delivered. I only activated one mobile router and the second mobile router was not activated. I was charged for two mobile router. I then escaped the matter to the sales consultant that assisted me, Lugeshni Pillay. Lugeshni advised that the second router will first have to be collected before I can get the refund etc, note that there was no remorse on this mistake because my business letter was clear for one mobile router and not 2 & she didn’t have a remorse of the mistake she did. The mobile router was collected but still not refund etc, statement dated 3rd of October does still show a deduction for the second mobile router. This means I been charged for the second months for a device that was collected. No one has contacted me that they have received my mobile router and I don’t even know what is happening.

I am hoping for the senior manager to contact me directly and provide me with detail feedback and hoping to get refund due to me and hoping this error of deducting in my bank account for an item that I don’t have will be resolved urgently,
