Poor Customer Service

I am hugely disappointed with the customer service received from Smeg. My kettle was returned within warranty as it randomly stopped working. I received a replacement which was not with the same specs of my kettle. There were no numbers on the side and the paint was peeling off. I then had to return it again to which I received another replacement which was leaking. I had to return this one again. I then received another replacement which was not the original colour of my kettle. My other Smeg products are all green and I explained this to the person. All she said was she does not have stock and will replace it once stock is received. I have been inconvenienced by Smeg and nobody seems to care about this. I’ve been following up constantly and all I am told is that there is no stock. Is it the customers problem that Smeg does not have stock, this does not constitute good customer service by any standard.
