very bad service

I bought a Lenovo laptop last year for R6000 which has warranty of 3 years. In March the laptop started given us problems regarding keyboard. We took it in at the Glen mall as that is where we bought the laptop. The guy by the name of Stanley booked in the devise, the following week he called as to ask for the password which he was given. I was informed about 14 days to repair the laptop. On the 21 of March I decided to follow up since I did not receive any feedback. I therefore spoke to Stanley who told him he was not able to lock in to his PC to see the progress but he will call in as soon as he manage to log in. After 30 minutes I received feedback from Stanley who informed that their still busy with my devise their waiting for parts from Korea and it might take longer due to Corona virus. To my shocking surprise I received a call from David who now tells me they’re not able to fix my laptop because it was damaged by water, when try to prop with him to understand why is now my laptop diagnosed with water while I received feedback that my devise is awaiting parts and their busy with it. this came as shock to me due to the fact that am fully aware that the laptop was never exposed to water since the laptop stays in my study room and in my study we don't eat nor drink. It is impossible for the laptop to be exposed to water. It seems like now that incredible connection does not want to play their role their blame shifting. David emailed me the quotation which is prices at R5338. Which is very shocking taking in to account the main primary price of the laptop which is R6000. When I was probing for more clarity as I did not understand why am told about the water. His responds was that is not his business he just called me to tell me about the quote that I must pay. I requested to speak to his manager he refused, I also did send him to emails requesting for his managers details he did not respond to my email due to the fact that he does not care about my concerns. Job JCR38473. I think it is very unfair to be expected to pay money that is equal to the price. This is day light ******* as this means incredible is trying to find ways not to adhere to the warranty. Their well aware that laptop on the day on submission it was never exposed to water. This is poor service all the fact that employees are not even willing to provide client with manager’s details. I requested to speak to a manager they refused requested for contact details they refused.
