bad service and *****elent

I did a purchase of a Sunbeam Blender at Makro Ottery in April 2021 and with a 12 month warranty and now only in October it nolonger goes on. I went to the store and they said l bought it online and they said will give me a credit note of which when l went to get the same product the price had gone up . they refusing to swap the product saying the price has changed and l did ask if the price has changed which my money has also lost value by them. they changed the story and said it was an online payment so l wont be able to get the money.

my question to them was why the money cause when l bought the item l knew its gonna last me more than 12 month cause of the warranty now l had money in April and the product never lasted and the money is useless now and they only wanna return it to me

always verify the warranties with those guys cause first they act surprised and next they dont know how to assist you
