Unhappy customer

I am writing this review with a heavy heart, On Saturday (6-01-2024) last weekend I went to a store to complete my application after I was assisted by one of the sales agents in Cape town who was very helpful and professional(Jermain Visagie). I then went to the branch and everything was okay until came a time where today (08-01-2024) they phoned my HR where I work at Momentum Metropolitan ltd which is one of the biggest corporate companies in south africa and I work there as a service consultant assisting hospital and surgeries on a daily basis with peoples lives since I work in a health sector and we assist our patients over the phone. I was told that I cannot get furniture since I work for a call centre, even after I produced my payslip and contract of employment that I do not work for a fly by night company it is a very professional corporate division, one of our HR persons had to again send a details email confirming my employment but still no assistance. My question is why I am being discriminated like this after I approached the store and asked to purchase furniture of which this increases sales. I have gone through a very long process with the application i would like this to be attended to ASAP
