So unprofessional and all different responses

I was awaiting a bank card delivery from CCD this passed Monday. Monday came & CCD could not release my card to me as my proof of address was apparently wrong (a account statement with date not older than 3 months). The delivery person then told me he would come back the very next day & same time to drop it off (giving me time to get the correct documentation). Next day (Tuesday) I received a call from CCD asking can they drop it off Wednesday, I asked them if I could fetch it by their offices today instead & they agreed. I also asked them if I could use my fathers payslip with our address on it to confirm residence & they said yes I could. I arrived by their offices & all of a sudden they change their minds & say I cannot use this as proof of address. They then say I could use an account statement instead which I originally produced. They are really messing me around. My father also received very poor service from them this past month.
