Customer service experience at Pep cell Zebediela store

I visited Pep cell in Limpopo zebediela moletlane and this is what I experienced at their store.On the 27th April I made the purchase of new DSTV decoder for R700 with intention to install at my new home and few minutes I changed my mind since there is no one living there and opted to return the unit with everything still intact and the seal not voided back to the store and the lady named Abigail told me that she can’t help me return the unit.When I asked why because the unit is still the same condition why can’t she take it she never gave me reason.I asked her to refer me to area manager so I can ask why they can’t take the unit back and she refused but instead around 12h40pm before the store closes called centre security so they can remove me out of the store for requesting area managers information.I left both the decoder with proof of purchase at their store .Last week Tuesday I called their Head office in Cape Town and the lady refer me to send emails address so they can quickly escalate the matter.Tamzyn Munnik is the person responded my matter and gave me turn around time of 24hrs for the area manager to resolve the matter.Wednesday ,Thursday was public holiday they were not working.Friday I called and asked why my matter is not resolved yet and I got no response .I still not been contacted still and not been refunded my money back yet their stuff is with them in their store.
