Bad service

Vodacom empangeni-sanlam centre. I recieved a poor service... I had their screen protector in December and I was told to come back within 6 months if it gets damaged and I only got the chance today. After I had explained to the sane person assisted he asked for a damaged one I told him I don't have I only have the receipt he told me about, he then took my phone and invoice and assisted another person after 30-45 minutes wheb he was done only to tell me I can't be assisted without even communicating or trying to verify his information... Name of the person assisted written as 15-LUBAB001 ON THE INVOICE, THE SAME PERSON WHO DISRESPECTED ME
