Bad quality doors and aftersales service @ Leroy Merlin South Africa

We bought 9 of their 8 panel doors, which we recently installed. Once installed the panels started to move leaving gaps in the doors. I then contacted the head of department at Fourways but his response was not satisfactory. I then contacted head office via email and telephonic but NO RESPONSE!!!!Please refrain from buying anything from Leroy Merlin because their quality and aftersales service is not a match compared to Builders Warehouse or Chamberlains!!!!
