Staff not willing to assist.

I bought a cellphone for my daughter in December. Over the last few days she struggled to get the phone to charge. On Saturday I took the phone back to Centurion store and they referred me to Connect, the guys at Connect checked out the phone and told me to take it to Edgars as they get quicker service. At Edgars, they checked out the phone and after trying to charge it seemed okay. At home when we put in the charger it got stuck and the charging block broke. I took the phone back to the Jet stores in Quagga center on Sunday and was told that they don't take in phones over the weekend and I must come back during the week to hand in the phone. Yesterday, I rushed from work to take the phone back at Quagga and was told I must go to Centurion as they don't have the forms. By this time I was very annoyed and grabbed my stuff to leave. As I was walking out the lady shouted that she could see if she can find the forms - why did I have to get angry first. She was talking to her manger and debating if they should help me. I find it totally unacceptable that I should be sent from store to store and still get attitude from staff not willing to assist.Should customers only shop at some stores
