Complaint about customer service

18/12/2021 i bought a router at Vodacom Bushbuckridge. Tested the router only withought opening the charger package or any other thing inside. 19/12/2021 i took the router back as it was not working and the shop people were rude and said i should return back later as they did not have the money in the shop.

I went back today and they tell me that they cant give me money as apparently the charger is dirty.. I asked them how did i make it dirty as i brought it to them and their technician tested everything so how do i fix this issue now.

The ladies in the shop told me its not my problem and they walked away.

I dont know how you plan on resolving this but the staff at Vodacom Bushbuckridge in Mpumalanga need to be tuaght how to talk to customers and handle situations better...
