Extremely bad service and caused a negative affect on my credit profile

I called edcon call centre on ********** 442. Spoke to 1st consultant and she jst makes up her own rules as the previous day i spoke to another lady and she could call out while on the line with me. She tels me to hold for teamleader amd makes me wait for over 10mins because she didnt want me to speak to her teamleader. I dropped and called back and request to speak to team leader and she also gets annoyed because i refuse to tell her what previous lady done and also puts me on hold for a while so i dropped. All i want is for edcon to update our payment as it is going to affect our profile negatively. Payment was made in store on 30 November i have sent proof of payment. Edcon replies back i have to go to store as they havnt updated payment. They are one company! Why can edcon not just fix the problem with the branch..why is it my duty to go to store when i pay on time!
