the worst service i ever experienced

I have been liaising with Ridhwa at Performance brands for close to a month now regarding swim suits i bought for my kids. They used the swim suits once and i bought it this year February 2018. The clothes stretching and deteriorating. I took it back to sportmanwarehouse retail crossing where Patience helped me so kindly and sent it to performance brands. Ridhwa at performance brands has no customer experience s****s and will respond to emails when she feels like it. After settling for less as i was suppose to get a full refund or replacement for clothes used once and not even couple months old they only want to give me 50% off buying new swimsuits. i decided to take it and now i will have to wait another week or so as Ridhwa has not responded as yet. Can performance Brand please invest in there Staff they hire and sent them for customer centricity workshops.
