Bad service

Hi<br> <br> I closed my Standard Bank blue beam credit card in March 2015 and it appears it has not been closed as yet. I tried to apply for a Cellphone contract on the 02 December 2015 just to find out I have negative information @ Experia (credit Burea). I called Experia they told me I have a R25 outstanding on my Blue Beam Credit card which is the reason for the negative information. I then called Standard bank blue beam and they told me they did not update the information on their side reason why the problem. I am very unhappy as I passed on a cellphone deal that has now been closed on the 12 December 2015 and the problem is still not resolved. I Cant believe it can take so long to resolve this problem.
