Complaint

I purchased a Toni & Guy flat iron couple of years ago still under the 5 year warranty. I have taken good care of my iron. Recently it has been giving problems as the plates are not heating up or either just 1 of the plates heating up. Went to clicks in Goodwood Mall to seek advise and they said they cant do anything. I know I dont have the receipt but I can get my bankstatement to prove the purchase. If it was purchased on discount I would understand however I paid almost R900 for this flar iron...really dissapointed.
