Three months wait for a one month old watch

Purchased a Tempo watch at Canal Walk store on the 27th November 2015. The watch was working intermittently, took it back to Canal walk where they advised that we take it to some sub watch store that replaces batteries etc however the guy that does that wasn't at the store that day when i was there. I then went to Parow centre where they changed the battery for me, it was working but the next day stopped working again. I then popped in at Parow center again where they advised that i will need to take it back to Canal Walk store(which is out of my way), i never got a chance to go there and time was not standing still, I decided to go back to parow and ask for another solution as i am unable to get the time to go to Canal walk. The sales lady then advised to book the watch in, which i did and after two weeks went back inquiring how long it will still be, to see on my till slip that ill only receive it on the 03/03/16. I do not think that its fair to wait for 3months to receive a watch back for repairs that is one month old and has not been working since day one. I would like to know what my way forward is.
