I brought a watch that said you can swim with it and when we read the instructions it was clear you could not put the watch in water. Takealot sent it back Firstly without its charger and saying we took too long to return it. So now we have a watch we can't charge that is not what we wanted. I can't get hold of anyone and I am now very upset with their service.
