Dissatisfied with Russel Hobbs

I bought a Russell Hobbs kettle at Makro Bloemfontein, so now the kettle have been giving me a problem. Took it back to Makro as i was still within the 2 years quarantee, upon arrival we were told it'll be booked for 6 weeks for repair. Which the sales person who assisted us with the sale failed to explain that to us, okay we fought but eventually left the kettle. Was realy disappointed as i always buy their small appliances and never had to wait 6 weeks, waited and they called to come and collect which we did. Only to find the kettle still have the same problem even worse because it just turns off whilst is on without boiling the water. Im realy disappointed as now you have to hold the kettle for it to finish the boiling process.
