They know nothing about communicating with their customers

I have been recieving messages from December that my card will be delivered, this never happened. When they finally reach out to find out where they should deliver my card, they got my address completely wrong. They said my card will be delivered on Monday tuesday the 17th Jan but cancelled while i waited for their delivery to say it will be on wednesdaybthe 18th Jan. Its past midday and i call into their call centre twice to find out what time their delivery will be as i have somewhere else to be and their call centre hung up on me twice. ****ty service!
