Refuse to honour warrantee.

I have been an Samsung supporter for years and only write on this platform out of desperation for a company I used to hold in high regard and refuses to honour a warrantee. Broke screen of phone whilst under warrantee....paid to have it fixed at SAMSUNG STORE WATERFRONT. Took ages and was then returned unusable as would not hold a change. Return numerous time IN WARRANTEE PERIOD for this same issue and at various times they lost the phone, gave me wrong phone and finally returned my phone STILL NOT holding a charge. THEY NOW CLAIM MY PHONE IS OUT OF WARRANTEE AND REFUSE TO REPAIR IT. ALL THE ABOVE IS IN WRITING AND NOT DISPUTED BY SAMSUNG SOUTH AFRICA. I have written to them many times and reply still claiming out of warrantee....but for last three months saying escalated....BUT STILL NOTHING. I have written to senior management....no reply until I was told by the complaints department to take to Ombudsman!!!!!! To me it is shocking that SAMSUNG SOUTH AFRICA will not honour the warrantee....and I will not accept such poor service of an outstanding product. They must either prove I am wrong....or I will escalate to head office in Korea.
