Poor service in fixing a watch

I bought a Huawei smart watch from Totalsport. My Fiancee went swimming once & the watch broke & it's supposed to be waterproof. Then I returned it to the Waterfront store on 10/01/22 & they took it to repair it. Then after hearing nothing from anybody, I phone the store on 31/01/22 & they tell me that the watch is there. So I go there & get told that they were mistaken & the watch that came there was for someone else. So they waste my time. Then I get a call on 10/02/22 telling me that the watch is done & being sent to the store. So today I call the store to see where my watch is & they tell me that Huawei is still fixing it. So someone or everyone is lying to me. Your service is pathetic & I want a refund. No one knows what's happening or even where my watch is.
