Angry and frustrated

2months ago I bought winter items for my son from Naartjie. The track pants tore within a few hours of being worn and I had them returned. Because I didn’t have the proof of purchase I was told they were gonna be repaired and I would be called back. Yesterday I decided to pop in to check on the progress and to say the least the service was appalling!! The staff just starred at me as if I was crazy and could not give me answers. I requested for a manager and of cos there was no1 on duty. I left my contact details for someone to call me back..to no avail. We pay a lot of money for better quality and service but this is totally unacceptable. Can someone call me back to resolve!!
