BAD REPAIR SERVICE

I bought a watch in April 2019. In Jan 2021 the stones came loose on the face of the watch. I went to American Swiss East Rand Mall and they confirmed that the watch was still under guarantee and that they will send it in for repair. I was told that it would take 6-8 weeks. When I went to collect the watch I was told that the watch was not working. I told them that the watch was working when I gave it in. The lady who received it were there and she confirmed that the watch were working. The manager Lizelle then said that she would send it back for an urgent repair promising that she would push it and I would have it back in 1 week. I did not have any response from her after a week. Every time I call she says that she is receiving a parcel on that day and that she will call me to confirm collection. It has now been 3 weeks. She told me today that she has no idea when the watch will arrive and there are no one she can call to check to confirm.
