Horrible treatment towards customers.they make mistakes and force the customer to pay for it. re train your staff of what is customer service please

On the 5th of February I went to Stern's where I purchased many years ago mine and my husband's wedding rings. I asked for it to be resized to a size and a half biggest both. the consultant Vuyokazi helped me she asked the other consultant Diago to confirm if it was gold and what carrier it was she then said the system is showing her for both rings because of the information it will cost me R838. she asked me can she proceed I said yes she confirmed it's for both my work colleague was with me. she said it will take 4 days then I will get a sms to collect. 7 days went by I decided to call to see if it is there because it's pass 4 days. she said yes I then went there late afternoon to collect she gave me my ring then looked for my husband ring she said she did two seperate book ins so now I must pay R838 plus R485 for my husband ring I told her this is not the information she gave me when I came the 5th and now I'm being forced to pay for a mistake she made that I was in aware of. I told her I refuse to pay that was not the agreement. I told her to call her manager she said she is off I asked for the area manager she said the area manager is off I said call the regional manager she said the regional manager is in hospital. they will give me a discount and I must then pay R300 for my husband ring or it will be withheld from me because the store has already booked it in and paid for the repair. after I'm explaining to her the guy next to her Diago was there that day and my work colleague who came with me to collect said that this is not what she said that day of booking in. she says to her work colleague infront of me please take over I need to go to the back to drink sugar water because my blood is boiling now in my face and walked away. I still have recieved any call to resold this from the store manager/area manager or regional manager. the disrespect and treatment I got was horrible. I had to pay the extra money for my husband ring or she said I would not be getting it back what type of customer service is this! disgraceful. never again will I support this store . Stern's Greenacres Mall EC branch code B 015088. Vuyokazi said the name of the manager is Nefdelene and the area manager Noli Vetche.
