unhappy vodacom customer

upgrade of longstanding vodacom cellphone contract done at Sandon city Vodacom4U store on 23/12/2020. product Samsung S20FE bought. upon operating the device front screen started to heat up to the point where it was unable to be held to the ear to speak. same heating up issue when the phone was left to charge. the soonest we could get the phone back to the store to report fault was the 27/12/2020. being very dissapointed with the quality of the Samsung S20FE and having lost trust in the brand i instructed vodacom to cancel my contract. i was even prepared to take a device of even greater value from the same store. The management and staff at the vodacom4U sandton city store were extremely rude arrogant and unhelpful. They refused to acknowledge the phone had a problem even though we operated it in store and they personally felt it heating up. reluctantly they booked the phone in for repairs with Samsung, and somehow the fault report came back negative as well. the problem with the phone persists. ive asked them to rebook the phone for fault checking with Samsung out of shear frustration, but it seems like both Samsung and Vodacom are bent on forcing me as a loyal customer to pay for the next 2 years for a device i am extremely unhappy with and unable to use. dissapointing and disgusting service from both vodacom and samsung. until today 12 january 2021 still without a phone.
