PATHETIC SERVICE- Diners International Credit Card

Utterly pathetic service received from Diners Club South Africa.I used my card to book a trip and notified them that I was traveling abroad.As a business owner,my payments do tend to get delayed.Diners decided to block my card until payment was made (Fare enough) I made payment of R33500 that I owed them on the 29/07/24.They then advised the card was now active which i really needed as i was in a overseas country and really wanted to make use of their card as thats their catch line with the card being a "International" card.On the 01/08/24 literally 2 days later my card gets blocked again because diners decided to debit my account for the amount which I paid 2 days prior.Im currently now sitting overseas in a foreign country with absolutely no access to my credit card which should be active.Iv sent them over 5 emails and have not gotten any reply from them.Truly pathetic and I would never recommend them to anyone.Utterly pathetic service.They extremely responsive for you to pay,but useless when you need to use their service. Definitely not worth it.(Their job is to reply to emails so I don't understand how they cannot respond to mails)
