CLICKS ON LINE - FAILED AT KEEPING ME AS A CUSTOMER HAPPY

I returned a power bank, in December 2022, they informed me, that the product was out of stock, So I said, I will wait a little while, It is now 3 months, and they haven't sorted out my replacement. I have sent numerous mails, asking what is going on, all I get told is, it is out of stock. I don't want my money back, I want ss working power bank. Is that too much to ask. If they were customer focused, they would have brought a different power bank, same power, just to keep me happy !
