LG G4 Stylus faulty

I took a contract out with telkom mobile. It was an online application about 2 months ago. The LG G4 Stylus. <br> <br> 4 days ago the fone just stopped working. It says emergency calls only, yet the mobile data still works.<br> <br> I phoned Telkom mobile and they suggest that i take the fone back cos it looks like its a hardware problem.<br> <br> I took off work today to go to a Telkom Mobile Office.<br> <br> The lady tried everything. Even did a sim swop. Nothing helped. <br> <br> I informed her that we currently shifted and i lost the delivery note paper but I do have the box and everything. <br> <br> She informed me that she cannot book this phone to be fixed without the delivery paper.<br> <br> What am I to do now? The fone is not even 3 months old and its useless!!!!!<br> <br> I am currently sitting without a phone now and defnitely not financially strong to take out another contract or buy a new phone!
