Pathetic service on new mobile phones

Hi My daughter got a new Lg G8 as upgrade Sep 2019, great phone…. Earlier this year the phone fell and damaged the screen. LG SA referred us to Executronix to have it fixed. Now after months of back and forth, I had to pay for an assessment with the answer that the phone cannot be repaired as LG cannot supply spares. How can LG not have spares for a phone that is just more than a year old? Now we had to find a replacement phone for her to use, I have to pay on a contract where LG cannot fix their own phone…pathetic service LG. We will never buy any LG products again and I will tell everybody how bad your service is. Adie
