bad service

I bought the shoes(R1700) 2018 June at Green Cross Kolonnade helped by Maria(manager) in 2019 Nov sent them back to the shop for exchange which she did. In 2019 April complained about them experience same problem at the same spot and also inside at the back(heel) of the shoes it feels like there is a hole.i was told to bring slips,i look for them but could not find and went on leave for three weeks.i went back again to also complain about 1 shoe coming apart at the bottom,she said she can't help me because they were more than six months.i wrote email to customer care and send shoe pictures to Laura Robinson and she said i must go back to the shop Maria can decide what to do with shoes,when i get to the shop she said no they are more than 6 months,i left the shoes and suggested them to be taken to the manufacturer for assessment and send them back with certificate to show that they saw them.After a week i went to buy new pair of shoes and she asked me if i received a call from head office i said no after a week i went and she made a call and said they will call me back and i left,i received a call same same day lady on the phone said she is the aria manager and she said "sorry we send your shoes to manufacturer and they cant help me they are older than 6 months and when i asked her where about shoes she said they were delivered to Kolonnade shop today,i went and asked for shoes and certificate Maria said she can not give the shop email which is not what i was asking for.i left them there she said she will organise meeting with head office for me.No certificate No money No shoes im left with nothing.instead of helping me she said "I'm imtimmidiating her in front of her staff".Honestly this is not what i expected from this shop i have never bought most of my shoes from them but THIS unacceptable.
