Misleading and pathetic service!

I ordered an FNB SIM (Talk max) which states that it would be delivered in 3-5 working days. When I ordered it I got the notification with the self portal link and tracked it, everything was going fine and it still stated on the Self Service portal that it will be delivered today latest tomorrow the 26th of August 2020. So I got no updates during the course of the day which I still thought is fine because it will be here tomorrow as stated. BOOM was my bubble burst when I just got a SMS stating that delivery will only take place Friday the 4th of September 2020.... Well the way I feel you can delivered it to someone in Russia. Why advertise 3-5 days? This is misleading, I ordered it on that specific date for a reason. I called in and a lady answers the call. I asked her whether she can help, she stated yes and when querying this she tells me to call back between 8-5 and the people that can help left at 5 (call time @ 17:05pm) The worst service ever from a provider! Now I am not even sure whether I should still keep my account with you.
