Poor customer service

Two weeks ago I called to get a discovery credit card. Everything was done over the phone and that process went well. They told me that they will deliver the card within 3 to 7 working days. On the 3rd day a consultant from FNB called me and they told me that the delivery company came but my phone was on voicemail. I told him that I never received any call and he checked on the system only to find that they were using my old number. I had an FNB card 2 years ago so FNB has that number on their system and that’s the number they used to call me. I don’t understand whose bright idea was that because when I joined discovery card I gave them my new number. The consultant from FNB said he has updated my number on the system such that the delivery company the number they were supposed to get in the first place. I waited 4 days and nothing happened, I called discovery and they said the delivery company came again and my phone was on voicemail. That’s when it all started, I was put through to make arrangements with the delivery company through discovery. They told me that they see my old numbers on their system and they don’t have authorization to change my numbers. I have been calling discovery and their delivery company for 2 weeks now. They have very poor customer service and the delivery company they are using is useless, they have been saying that they will come and deliver the card but they never did and when I call them they say they did come but I was not there. They are a bunch of *****, discovery is very ***** and they have the poorest customer service I have ever experienced in my life. I don’t recommend anyone to get a discovery credit card, save yourself the stress of experiencing a company that doesn’t know how to handle customer issues and failures in their systems because clearly their systems don’t talk to each other and that becomes your problem as a customer. Till today I haven’t received my credit card, I am tired of calling them they can keep the card if they want.
