No card after 2 months

I opened a Credit card almost 2 month ago. I received 1x Amex Card, however on my App there were 2x Amex card as well as a Mastercard loaded. I cancelled the one Amex card and to date have not received a Mastercard despite following up numerous times. I can only see the cards on my app but not the account and transactions that goes off. I cannot access any statements as none is available, yet there is money deducted but I don't know for what. I am tired of following up on this!! I will have to close this account as fast as I opened it as the service is terrible
