Dissapointed on exchange policy

I am dissapointed with service I received at game gateway, I purchased a Russel hobb kettle last year October which I paid 600 for and I loved the item, in July I brought it in as the element was burning, it was cleaned and given bak to me, again I had the same problem I brought it back in september it was cleaned again I explained to manager nkosinathi I am not happy the element still has rust marks on it he refused to replace or refund me telling me to leave with wat was done!
