Vodacom Repairs Sandton City - Unfair treatement

On the 5th of December I took my iPhone Xs Max to the Vodacom Repairs Centre for a faulty ear piece and losing data signal randomly. This was a replacement phone as my original phone gave me issues 6 months into use. It had a poor sound issue from the speaker of that one. The following day I was advised that the replacement phone would be repaired and was out of warranty. So I needed to pay 15 thousand. My original phone was purchased on the 4th Dec 2018. The replacement was provided in May. I queried why I was not advised that the replacement had a new warranty period and requested Vodacom's complaints procedure? Instead Dina at the store ignored my email. I had to mail her today and only today does she then tell me to come get my phone at the store. To top it all off upon arrival I was asked to pay a quote rejection fee. I was never told about the fee. I believe that I have been unfairly treated and am now left with a phone that is even worse off than the first one. I would like someone to contact me to resolve the matter. I have the emails at Proof
