Poor Service from Vodacom Vodaworld

On 23 May 2021 I renewed my contract with Vodacom and purchased the Samsung ZFold 2. On 4 July 2021 'Ink Patches' appeared in the 'flip screen' and the phone was taken in for repair. The flip screen and the the protective cover was 'replaced' however the workmanship on the flip screen is very shoddy and an inappropriate protective cover was installed onto the front screen. Have brought this to the attention of Vodacom however to date no assistance/rectification has taken place.
