Telkom Trade Route's pathetic customer service

A brand new Samsung Galaxy S5 that I purchased in November 2017 just froze after only three months, so on the 12/02/2018 I took it back to the store to have it repaired. I was told that the repair centre would be in contact with me about it. Around the 26.02.2018 I received an SMS to say that within 4 days my phone would be sent to the store for collection. I went to the store on 02 March to collect it but the store was closed and a note was placed saying that it was closed as of the 01 March for renovations.The repair centre confirms that a Telkom employee received the phone on the 28.02.2018 but nobody from the store had bothered to call me informing me of the store closure and that I should please collect before the 01 March. They did not even send it to a nearby branch. So I have no idea where my phone is and how to get. I find this very unprofessional and I have been hugely inconvenienced as I am without a phone for a month. The store personnel cannot be reached and even the mall's centre management have no idea when the store will re-open. Countless queries to the Telkom call centre has proved futile as I am pushed from pillar to post without assistance to get my phone back.
