Unprofessional Behavior

I do not understand why I had kept my Diners Shariah Card back in 2019. I did post a review here back than. Maybe its my ignorance or shallowness that made me keep this ridiculous card. Stupid me. I am a sucker for being degraded and disgraced. That's me. I get a call sometime last year for me to provide all my details and documents as they require them, once again. I had been paying all my fees, getting all the correspondence and paying towards the rewards programme from this unprofessional company throughout 2019, 2020 through mid 2021. How *********** and unskilled is this company namely, Diners Club and more over Standard Bank South Africa, who deals with issuing Diners Cards in South Africa, as they are requesting this information from me again. How is it my fault that someone did not do their job in capturing all my info. Why would I need to verify all this information again as I did before, I have all documents on file and emails when all this had been sent through. The card had been issued, with a monthly limit and a pin, for purchasing as well, and now this. My purchases and payments had all been fine. Come May 2021 using my card, I find that this card had been constantly declining. Being utterly humiliated when attempting to pay, and resulting in the card being declined was a bit of an irritation. Contacting Diners, to understand why this had occurred, I was told by an individual that my documents had not sent, and I had told the agent who requested this information, from me, a while ago that I will not give all this information a second time. The individual, as always could not give me any further information and is merely reading the notes placed on my account by a previous agent of the company. Poor guy who was of no assistance to me. Why did Diners not send me an email stating the current situation instead of suspending my card? Standard bank is constantly advertising Shariah products at the moment. Please do not forget to mention how unskilled and inexperienced the Diners Shariah Card and their employees remains.
