Bad customer service *********** manger

I recently bought a Zoe cannon mini from the canal walk store and the product did not want to switch on after being charged for over 3 hours . I returned the item and I was told to come back to canal walk the next day which I refused , I was then told I will receive a call the next day which I did not receive. I had to call them and i was pushed around from departure to departure and then they dropped the line on me. I called back an hour later only to be told by the manager that I have to wait another 24 hours for the branch manager to call this to be rectified and for my refund to be processed. I am expecting some token of apology for the inconvenience I was put through , as well as my time and airtime being wasted over an issue that couldve been resolved on the same day i returned the item in store.
