Bad service and non communication

<br> Hi I have been sitting with a problem got the phone on the 12 December 2015<br> after 2 months it started with problems just freezing going off and no sound<br> I have send it it for repAirs on the last week of February thereafter 4 weeks I<br> got it back end of March and having the same problem freezing going off no<br> sound and now it does not want to switch on they said they did a software<br> update and phone is working it is not. I send it in for repairs again where it will be priorities but now they said I am not the only customer so what does priorities mean. Nothing . I have been emailing cell c and Samsung and when cell c is calling they say it takes time. That is not a answer. They got the phone for 4 weeks they should have fixed it the first time
