Worst after sales service

i had a problem with my Samsung galaxy s6 edge,this phone wont pick signal and continuously drops signal.Took the phone into Samsung and they advised the software needs to be reloaded.After the software reload the phone continued with the same fault.Samsung then advised there is no stock of the mother boards and i will have to wait a month for this to get fixed.After making a noise they then decided to replace my phone but heres the best part,i was advised it will take ten days it has gone to almost 15 days and still not yet resolved.This is ****py service for a premium branded company with supposedly premium products.<br> <br>
