Unacceptable Issues with Payment system

When paying, there is the option of using points and card payments. When I did so, it accepted my Ucount points but not my card payment (points were deducted from account but not amount outstanding). Error message said to call in which I did. I was then told I had to send a statement showing points deducted which meant I had to log into my account which I then had to reset the details for as I don't use it often (sms notification was not sufficient notice apparently). I then had to email everything through and was told a voucher would then be issued. When I was placing the order online, the delivery time was stated as same day before 7 pm however the person dealing with the enquiry advised this is not so. No I have a half paid for delivery that won't even go out on time. Not very impressed.
