Poor service

I booked my Galaxy Z flip 3 on the 14 of September for a screen replacement I was advised by the consultant that the device would be ready withing 7 days, furthermore I advised the consultant that I need the phone before the 2nd of October as I was leaving the country, I was assured that the phone will be ready. I called into the store a couple of times to follow up and I was Advised that device would be ready at the end of the week, I waited it was not ready I continued to have patience waited for the next week called in was told it will definitely be ready at the end on the second week I waited again called in that Thursday pleaded with them I needed that device as I was leaving the country, I waited the entire to get a response about the device they finally call at 5:30 to tell me my device is not ready, the next day I visited the store extremely upset spoke to. The consultant at the front desk asking for updates on my device and he was unable to even tell me after 2 weeks what is going on with my phone but gave me nothing but excuses , I left the store called Samsung headoffice reported my incident had a very helpful gentleman by the name of Vaughn who called in to the store for me spoke to who I assume is the manager and tried to get some answers for me, the manager gave his word that he would call me back in 15 minutes to give me an update I waited the entire day and never received a call. I left the country without my phone I am really disappointed. Please to whoever has a need do not go the this Samsung service center the service is terrible you are better off driving out of town to get help.
