Ring for Repairs

We sent my ring in for repairs on the 01.12.15 got no response till we decided to go to the store and find outbut we were given a very very Bad attitude from Vuyelwa''The ring hasn`t come back from repairs yet''.They still didn`t call us for updates we went again to the store and got another lady who said shell give us feedback on Monday but they gonna charge us funny enough the slip shows its still under warranty.Got no call on Monday waited and I decided again to call the store,I spoke to the manager who said the ring is Un-economical to repair they gonna give me a new ring i should come on Saturday.I went and the Manager was not there and Vuyelwa gave us a very very bad attitude agan saying'we must wait for next week wednesday as the Manager is not there but I told her that we were told to come today.Please help us me and my fiancee are really unhappy for the service we got and also we no longer want a ring that costs R600 because really this is not on.
