EXTREMLEY DISAPPOINTED

After 4 weeks I still dont have my phone. I registered my S4 for 2 free replacement screens in 2014 (of which I've used 1 replacement). After a LOT of back and forth I'm now told that I registered my device before my contract started and I will have to pay R1995 to have the phone repaired. How could I have registered if I dont have the IMEI number. My contract states I received the device on 07/01/2014 and their system shows that I registered it before then. I was told to go back to my service provider and ask them when I really received the phone and change the contract. When I initially sent the phone in I was told that my contract didnt reflect the IMEI number. Bearing in mind that the first replacement screen done, these details were not requested and the screen was repaired within 1 hour. Then when I sent the contract, I was told it would be repaired but they did not have the parts and they would order the parts and I should get my phone this week (after I called to check what was going on). Now today I'm told I must pay as it shows that I registered before I received the device. I AM LIVID AND VERY UPSET. I will not take another Samsung phone again. <br>
