Hi I have a problem ...

Hi I have a problem with Bennett read I bought a toaster it only worked for six months I returned it to the shop Later they call to say I should pay R449 for fixing it,I told them that the toaster I still under warranty, I told them to return the toaster to the shop because I don't have money,last weekend I went to the shop to collect the toaster it was broken I don't know what to do I returned it again to the shop to say I didn't bring this toaster in this condition so they said they will call me,I am tired of waiting ☹️
