Bitterly disappointed and frustrated

I have a Hisense U989 phone i bought about 2 months ago at Edgar's in Bellville. About a week ago the phone started charging backwards, i would put it on charge and the battery life would just decrease instead of going up. Last night my phone just stopped charging, now because i took insurance for the phone and it is still under warranty i sacrificed my lunchtime and went to Edgars with all the necessary documents. When i got there i was given a pamphlet and told to contact Hisense ( ********** 3673) as now they have a service where they come to your work place and fix it for you on the spot. I did this when i got back to work on the the first attempt after correctly following the prompts i was asked to rate the consultants service without having spoken to anyone, i redialed and got through a lady who did not bother with her name, midway my explanation she cut me off. I redialed again and got a guy who also did not bother with his name and i explained my situation and he agreed that they offered such a service and while i was waiting for feedback after explaining i again got the machine which asked me to rate the consultants name. I went to their website and got an email address for customer service ********** which came back with a failure message saying that it does not work. I then used the number provided on the website ********** 260 and nothing. I am so hurt by this as i have been having problems with a relatively new phone for a week and now i can't use it at all. I still have the original packaging and charger like i was advised upon purchase by Hisense doesn't seem bothered. I am starving as i type this because i sacrificed my lunch time to do all of this only to be spat at in the face by the very same people i brought business and who are supposed to help. Where does one go from here
