Pathetic service delivery and dissappointed

I purchased a 11 fin Russell Hobbs oil heater about 2 years ago. At the beginning of the year i switched the heater on, it did come on however the lcd where you change the temperature settings was not working. I then took the heater to the repair centre on the 22nd February to have the heater repaired. I did request that the technicians do contact me with a quote before going ahead so i can weigh out my options as to whether i should repair it or replace it depending on the cost. Today i tried contacting the repair centre numerous times in the morning, there was no answer. I then sent an email to headoffice at 10h21 and copied in several other people that have been dealing with prior to the heater going in for repairs. Guess what i got no response until i tried calling the repair centre again which was at 14h15. I was then told that the heater cant be fixed as there are no spares. How can you not have spares when the heater is still being sold in stores. Doesn't make sense at all. Why would i spend so much on a heater to last me not even 2 years when we only make use of it in Winter....It is Russell Hobbs for crying out loud - our house is completed furnished with only Russell Hobbs appliances and now we get this....Pathetic excuse for a reputable brand
