MTN TURNING MY CONTRACT APPLICATION DOWN BASED ON MY RACE

I am absolutely shocked and appalled by MTN South africa. I am on the lookout for a good lte internet package as I use internet for everything including Working from home. After the dissapointment I have had with rains slow speeds and open serve not being able to provide fibre to my line I came across mtns package. 499 for 220gb and a router for 24 months. I immediately app****. I had a sales rep contact me take all my details. I even have a contract with MTN which is my phone. The credit check was approved. I earn a very good gross salary and my expenses are low. After 2 hours of waiting im told I am declined with no real reason. This is because I am indian. How can people who earn half of what I do qualify for this package yet im declined with no real reason and all my checks came back clear. I'm absolutely dissapointed in MTN for making it a race issue
