Good customer service I

Today I went to buy a new battery for my cellphone , I first went to Mtn and was immediately assisted by the staff and I got the price and I then went to Vodacom to get a price as well and on walking the staff 3 of them look at me but do not acknowledge that im there and look as if they looking through me(one of the 3 staff was busy) so I waited a couple of minutes but they still don't ask if I need assistance and I have ask them to help me , I got the price of the battery from them too , it was the same price as at Mtn , even though I am a Vodacom customer , I decided to go to back to Mtn and buy the battery I needed from them as they gave good customer service. Thank you to the staff at Mtn today. You made a customer feel appreciated.
