Bad service

Moved my smallest Bussines account over to them. Must say trying to do anything is a mission, from getting a credit card for the purpose of hiring a car , took them 3 weeks, just to see there is RO available on it when I needed for the 1st car rental, total embarrassment for us as a company, just to find out you have to put money in before you can use it to rent a car, what is then the point of having it. Yesterday I requested a Bank confirmation letter so that one of my customers can pay me, it is now almost 24 hrs later,3 calls later, and still no letter. They don't even have a place to lay a complaint.When you phone to complaint ,they cut your your line twice.
