Pathetic Service from Incredible Connection

I sent in my son's laptop which is still under warranty for repairs on 22nd May 2020. I received no feedback nor any form of communication regarding the repair. I called numerous times to be told that the go ahead has been given to repair on 02nd June. Silence for a few weeks and after numerous calls, they said the incorrect part was supp**** to them. I asked for an estimated date that I will receive the item but as usual no feedback nor callback. He has been using the laptop for his university studies and they are already working under stressful conditions. It is more than a month and have received no feedback as yet. Their customer service is non existent nor do they care about their customers.
