Do not support Belegi

I've been buying all my company's overalls, safety boots and construction safety signage from Belegi in Centurion for the past 3 years. On the 9th I went there to buy new overalls and ordered exactly the same as I always do. The overalls went for printing and when it was issued to the staff we realised that the sizes are incorrect. Instead of size 36 pants we were given 36 tops, and the pants 34. When I went back to the store in Centurion they were not prepared to help or even just exchange the pants as they only sell in sets. They checked the past purchases and said that I always take the sizes given. I took an old set and showed them that the sizes supplied in the past and the new ones are not the same. Again I was told sorry they can only go on what is on the sales slip. The manager phoned the owner and the same, will not help/exchange. After supporting them for the past 3 years my support just stopped. I will find another supplier and want to inform other companies do not support them, they are keen to take your money and even though they make mistakes will not help you to resolve the issue. Good luck to them, they are doing great and obviously do not need my business.
