Why have store phone numbers if nobody answers

I was looking to buy a cell phone that MTN is offering , so i phoned the following stores with zero answer <br> Sandton<br> Eastgate<br> customer centre morningside <br> bedfordcentre <br> fourways <br> stoneridge<br> greenstone <br> <br> A total of roughly 60 calls with no response, i landed up driving to eastgate,bedford centre and sandton with zero stock. <br> my advice is get rid of store phones and acknowledge there is no Customer service, it will reduce customer aggravation ,
