Disgusted with customer service and the quality of jeggings.

Last week around Thursday 21, June I went on the Pick 'n Pay website to lay a complaint about their jeggings that keep breaking after a month. It is now Monday 25th, June and I still have not heard anything from them. I stated in my message to them that I have been buying jeggings from them for the past year and everytime the jeans stretch and fray after a month of wearing them (on and off). I have taken a few pairs back for this reason but I still buy them because every month or so they release a new range of jeggings. Any normal person would assume if you are going to release a 'new' product exactly the same as the old, that the previous problems would be fixed. Pick 'n Pay is the only store that sells such a wide range of jeggings and you would assume that you would atleast get decent quality clothing for the price you pay. My most recent pair I bought a month ago and already they are worn through! Obviously I cant take them back because I no longer have the tags or receipt. I am so angry that I have had to buy a pair of jeans every month. What just makes me angrier is the fact that I have waited about 5 days for a response from Pick 'n Pay!
