samsung galaxy s6 edge

<p>I took my phone in at Samsung Polokwane in May this year for inside screen repair. They have send it to Cell Clinic. I know my phone was still working. I just did not see anything on the screen. Now they have quoted me R4887.66 for the mother board. What about the screen it is still under the samsung warranty. Did not receive alot of communication from Cell Clinic. Now I received a sms not even a complete sms said I must pay R250.00 before I can get my phone. How must I know what they did to my phone. Is this a sceem to make money or what. I am not happy at all. </p>
