Poor customer service

This is the worst customer service I've ever get.On the 27th December 2019 i app**** for credit card, received message the same day informing that my application has being processed and they will call me shortly and i did submit all the relevant docs they need.On the 31th went to the branch to find out how far is my application,they gave a phone to call,the first consultant who answer told me i must wait they will respond with in 5 working days,the same day i call again at the same branch and the second consultant told that my application is completed they are still waiting foe someone who works with cards but she can not get hold of her she is on leave but it will take 3 working days.Since then i have been calling to find out what is going on because no one give the correct,every time i call they will tell is approved and completed.I went to the branch we do it manually and they call to inform me that is declined because of the one that is approved.Today is the third week but still no respond to inform me what is going,last week Friday someone call me took my id number and said she will get back to me and she never did.If I don't call them no one call me to let me know what is delaying them .I am so disappointed,its like they don't care about their customers.
