Unacceptable Service: Vodacom Repairs, East London

Very unhappy with the service received from Vodacom Repairs East London @ Vincent Park. I took my Sony Xperia XZ1 in for a screen repair to be told that I should pay an assessment fee, even though I knew all I wanted was a new screen, and all I wanted was a cost for repair. Anyway, I paid the fee and was told that I would receive an SMS with a quotation for the repair. Literally 30min later I received an SMS stating that the device was ready for collection. I thought this strange and attempted to call them. After many failed attempts I was finally able to speak to someone for whom I gave the job number for clarification. I was then told over the phone that they no longer receive parts for the Xperia XZ1 and would not be able to repair the device. I enquired on whether they could reimburse the assessment fee as I was really paying for nothing, only to be told that no they would not reimburse me. Are you seriously gonna charge me R60 just to tell me you dont get parts anymore?! They could have told this to me in the shop, seriously. I expect to be refunded for the assessment as I am not paying R60 for nothing.
