Poor product and customer service from Incredible connections Tygervalley, Partserve and Lenovo South Africa.

I bought the Lenovo idea pad flex last year August 2021. I used the laptop for 10 months only when it stopped charging . I then took it to incredible connections Tygervalley in June as it was still under warranty until the 8th of August .I collected the laptop in July and was told there was nothing wrong with it. When I tested it the laptop had the same problem. I took it back to incredible connections on the 27th of July and was logged onto the system for repairs on the 1st of August. The duration of the repair was supposed to be 3 weeks but ended up being 5 weeks as there was an issue between incredible connections and the suppliers regarding the warranty expiry date. The issue was finally resolved and the laptops battery was apparently replaced by partserve in Johannesburg. I received the laptop on the 15th of September from incredible connections and was told the warranty had been extended by 3 months. When I tried to use the laptop again the laptop was still not charging, the charger was draining the battery instead so I took it back to incredible connections. I got told it would take 3 weeks for Partserve to evaluate the unit through incredible connections and fix it but 1 week if I take it directly to partserve. I took the unit directly to partserve in Cape Town and the unit was logged in for a re-evaluation on the 19th of September. On Friday the 23rd of September I called partserve where the unit was taken in for repairs and was told that the issue is now not the battery and is the main board instead. I got told that the warranty was for the battery replacement and not the whole laptop therefore I would be getting a quotation for the main board reparation . I have not used the laptop since June . It has been in repairs since June yet I am being charged for the reparation of the main board. Partserve failed to diagnose the laptop when they first evaluated it to identify the problem and still did not pick up on the problem when they had replaced the battery and said the laptop passed all diagnostic testing. I am dissatisfied with the customer service from Incredible connections and Partserve as well as disappointed with the quality of the Lenovo idea pad flex 3.
