Bad service on return of item at Take a Lot

I bought garmin watch in December 2023, in September 2024 I returned it, due to the kight at the back not working anymore and some data that does not appear in the watch. I handed it in on the 27th of September, got email stating they have received the watch. No communication further. I phoned them 2 weeks later and the person said he will follow up. Again no communication. I sent email, someone came back via email, stating the I will receive my watch when the courier brings it. On 28 October I went to Take a Lot in Richmond Park. The Manager stated that she will contact customer service as my watch is at the supplier and then they will send me an email to indicate the status thereof. But I am still waiting
