Pick n pay clothing

I have bought 3 pieces of babygrows 1 this past winter (6-12months) and now 2 weeks ago (12-18months). All three of them have lost the buttons at the bottom which is terrible because we can not wear it. I have bought one last year as well that was a new born same problem. I have washed it once and then the buttoms was gone so little one could not wear it at all. And might i add it was HANDWASHED. We live about 200km away from nearest pick n pay clothing so i cant return it within the time frame.
