Telkom not meeting obligation - supply of goods

I have upgraded my phone in-store at the Eastgate branch on the 9th of December 2017 and had not received my wireless charger. I have followed up in-store numerously and again two weeks ago, I was advised by the store manager Lebo Ensele, that he will personally attend to the matter and will give me a call in the subsequent week. Twee weeks later, I have no feedback. I am reaching a point where Telkom's obligation to perform its part of the contract has not been met for almost three months now and I have been paying for items that have not been supp****.

It would be wonderful if I someone can deliver or supply my wireless charger to me.
