Sterns worst service ever

I purchased a ring from Sterns Alberton through laybuy and collected it on 1 December 2022. and it has changed colours since, I phoned the store and the number doesn’t go through, tried getting their email and number again through the centre management but they refused to give them and told them they don’t have a phone line. I then contacted stern’s customers care and they requested the store to phone me and the little girl has been rude since. She closed the case TFG Customer, CS-*** is resolved. Regards TFG *** 0860-834-834 yet it is still pending. She sent me a WhatsApp to bring the ring to the store and when I took it in she said she can’t take it, I would have to bring it another day. So since she has my WhatsApp why didn’t she tell me not to come the same way she texted me to bring it Monday morning, now I must apply for leave again to bring the ring back,? The supervisor also started shouting at me and did not want to listen to my query. Alberton city stern’s employees are so rude and give sterns a bad name. I wouldn’t recommend sterns to anyone
