Worst service ever!!

I don't even know where to begin with this complaint. I app**** online to get an account with American Express. It was approved or so i thought as i received a sms instructing me to visit my nearest branch to collect my card. I went to your branch at Mall of the South. They were closed due to load shedding. Went back a week later was in the store for around 30 mins for them to tell me they could not link my card. The employee at the time called their customer service line and that again was another 5 minute wait. They too could not assist me. The employee then took a copy of my ID and said once their system is fixed and they can link my card they would call me. This now was this past Sunday which was the 2nd of October. The next day no one called so i had to call in only to be told system still not working they cannot link my card. I finally received a call yesterday the 5th of October and i was instructed to come in and they call customer service and assist me. So today been the 6th of October and now my 4th time back to the store i was again told system still down they cant link my card. The employee again called which i believe to be customer service and this time over 5 minutes for someone to answer spoke to someone on the other end and then hung up the call stating they could not assit me. I explained this was not what i was told the day before by one of your employees. A lady then came out from the back instructing her colleague to call again. And as always waited over 5 mins. I was in this store for over 40 mins today. Finally someone answered they explained the situation and was ordered to then hand the phone over to me. I was then instructed over the phone that i would be answering some security questions which i was not sure why as i have completed everything online. During this i apparently did not answer one of the questions correctly and i told the person on the call with one of the questions i was not sure as i didn't have those details on hand and she instructed me to guess. I was then told to hand the phone back to the employee she dropped the call and told me i now don't qualify as i answered a question incorrectly. The service both from customer service and in the store has been on of the worst i have ever come across. The staff in store dont seem to know what is going on. A customer came in and looked like she wanted to pay her account and was told they could not assist her. Another customer came in bought a watch paid cash and that transaction took just as long as what i was in the store. Well over 30 minutes. I have received numerous sms's American Swiss stating to collect my card now i am told other wise.. It has been such a mission to open an account with this company. Just seems no one knows how to help or handle customers. Why would i receive a sms stating i have been approved now all of a sudden i dont.
