Poor Mrp quality REPEATEDLY!

I bought a pj set ( I really really loved it) but then slept literally 1 night in it now it has holes. I'm not happy with this because how can you charge R200 for a pj set and then its R50 quality? What's even more disturbing is that this is my 2nd pj set that I'm buying with holes in. My first set I didnt even wear I returned it immediately as I picked up the hole before putting it on. When I returned it I got very bad customer service as if I'm the stupid one to buying poor quality things. I'm a very frequent customer I buy at least 2 items every week but I'm getting annoyed and discouraged at the quality Mrp is giving. I work hard for my money and if I choose to spend it at mrp least what I could get in return is clothes that dont break so quickly. This isnt even to mention my online orders that's always wrong but I feel too scared to go exchange it because I get treated like it's my fault when I'm in store.
