Bad Service

My Fiance bought me a Tempo watch &bracelet set.on Christmas day I find that the watch is not working.Monday 28/12/2015 my Fiance took it back where a saleslady said there is no more sets i have go an choose another watch.Today 2/01/2106 took it back again where Amanda said there is a set in Benoni and we can collect on tuesday they no way to check the battery in shop so I said why must we drive all the way again can we have our money back then all of a sudden Amanda found a little scratch on the back and she must 1st phone the area manager when i asked please do no area manager will not answer she is on leave .my watch do have a slip its in original package.why did Amanda made me feel dishonest?Now i have a watch thats not working.I would like my money back .Amanda never looked for scratches when she sold it to me.its very unproffessional to tell a customer you cant have your'e money back you must wait till my area manager comes back from leave.
