No service by Dell support at all

I purchased a Dell XPS 8700 desktop with a next day on site warranty for 3 years. Dell informed me in October 2015 to upgrade to WIN 10 and that this particular model was tested and is ready to be fully supported for WIN 10. I installed WIN 10 in Oct and all bluetooth and wireless connections do not work.<br> Dell Support tried now since end October 2015 to sort out this problem. Until today nothing was solved.<br> I have been shoved from pillar to post, spent 18 hours in the holding loop on their support line and was never connected to a technician. There must be hundreds of South Africans that purchased Dell computers, beware, there is no more effective warranty service available. Dell closed down the Indian support centre last year, all calls are rerouted to the UK and if you are lucky you will be patched through to a support center in the Phillipines as happened to me on 27. Jan 2016. I was told that they have to find a level 3 technician to attend to my problems. So far I am still waiting to be contacted since 27 Jan !!! NO DELL Service. So much for a next day full warranty service on site. Pathetic !<br>
