Bad attitude by staff and assistant manager

I went to the Vodacom shop lakeside on the 16th February 2018 to request my proof of upgrade/contract. I needed the contract so that I can take it to Samsung for repairs as it is still within a year. The reason I went there its because I bought my phone there.

Upon my arrival there I met a lady called Quennette (to be confirmed as I saw her log in with this name on the system), I gave her my details i.e. ID number and she could not find any information on the system. She then asked whether its my phone or business. I made it clear to her that the phone is in my name however my employer pays a portion of the amount. She further requested that I should go back to my employer and request a letter before she can assist me. Seeking a thorough understanding or reason to that she could not answer me as her focus was on her phone that she kept on responding to underneath the table - I am assuming she was on social media network like whatsapp or facebook. Then she asked her assistant manager to explain it to me. Assistant manager in a rude response without greetings said I should bring the letter from employer, my ID and the ID of my supervisor before they can assist me. As I try to ask or rather to get more clarity on why they need that especially the ID of my supervisor, she (assistant manager just left me). I asked the lady that its almost six months since I upgraded my phone with their store, when did they change the procedure. Unfortunately she just said to me, companies laws change now and then. she suddenly left me there and went to the office/store room, I waited thinking she will come back to me and all she did was sitting at the door and sip her water as she ignored me several times. The assistant manager was also busy with other clients. I found the above experience bit painful because my phone is damaged and I am stuck with it. The company that I thought could assist me could not even give me time to understand my story. the attitude was not good at all!!!
