Timberland Head Office(Abdullah)

I bought a Timberland Boot from Timberland Gateway in 2017 in 2018 the sole separated. Timberland replaced it towards spring 2018 and i do not wear my boots in summer so i happily stored it away and this year I pulled out the shoe and started wearing them in Winter. The worst happened and the sole started separating I returned the shoe back to Mall of Africa on 12/07/19 and the store manager Jabu who is very helpful was actually surprised by this and stated it will take 6-8 weeks which is fine with me. Today(15/08/19) I was contacted by Jabu and he said it will not be replaced so i requested the timberland head office number. After speaking to the receptionist I was put through Abdullah NOW this is where it's quite surprising when it comes to Customer support I was put through to ABDULLAH and he says separation of the sole is normal or I pulled the shoe apart and there is nothing wrong with it and maybe this brand is not for me. Timberland is quite a reputable brand internationally and the quality of the shoe is solid but recently there was a lot of returns from what I heard. Now back to ABDULLAH does he speak in this manner to all people who work hard and spend their money on expensive bands(Timberland)? I want a replacement of my choice because this shoe is quite expensive and this person who says I am destroying my own shoes needs to be dealt with by management. Please Contact me with regards to this issue ASAP.
