Disappointing experience

I went to the Sorbet at rosebank on Saturday 23 July 2023 and I must say I had a terrible experience. Firstly they did not ask or offer me anything to drink the whole time I was there but I took notice that they asked other clients. Secondly I was there to do my nails and the lady told me my nails would cost R640 but when I was done the amount was R945. This is my first time doing my nails at sorbet. The first design that I wanted to do they said they can't do it which they should be able to if they such a well known brand. I showed then a second nail set which they said they could do but the lady who did my nails did a very bad job. It's not professional, it's untidy and not exactly what I wanted. For R945 it is not worth it. I could have done it cheaper and better service somewhere else. I also had a R1000 gift voucher to use at sorbet and I took this opportunity to use it. Once I was done doing nails I went to pay using my R1000 voucher. The lady scanned the code and told me that the voucher is only R100 but on my phone it clearly said R1000. The lady kept on saying no it's R100 and she was extremely rude as if it was my fault or I was lying and trying to not pay anything. She told me to phone head office when it was clearly sorbet fault and it was the lady's job to phone their head office. This was very unprofessional of her. We phoned head office and they said they will sort it out. After about 15 minutes later the lady asked to scan the voucher code again and they saw it was R1000 and not R100. They did not even apologize. Overall my experience for going there the first time was so horrible. I did not feel I was getting treated nice the job they did on my nails was bad and unprofessional and the service I got was terrible.
