WHY HAVE A CONTRACT IF THEY CANNOT GIVE YOU A COPY

My daughter has had her Phone for 2 years when we upgraded the contract we were tol she will still be able to do an early upgrade now we are told the conditions changed and she will have to wait another year <br> The phone is on my contract and we spend plus minus R 2700 a month . on the 7th of August I requested a copy of the contract we signed I received an sms with a ref number S3-8DY2114V5Q<br> SAYING THEY RECIEVED MY REQUEST ONLY FOR THEM TO SMS AND SAY THEY DO NOT HAVE THE CONTRACT AFTER 2 YEARS REALLY THE STATES THEY HAVE TO KEEP CONTRACTS FOR 5 YEARS I WAS THEN TOLD TO GO TO THE STORE WHICH WE DID 2 WEEKS AGO HAD TO GO THROUGH THE SAME PROCESS THEY DO NOT HAVE THE CONTRACT SO THEREFORE I SHOUDL STOP PAYING AS I DO NOT HAVE A CONTRACT WITH VODACOM WILL CERTAINLY TAKE THIS TO THE OMBUDSMAN ABSOLUTALY RIDICULOUS
