DSV - PATHETIC SERVICE

I had lost my credit card and my bank fnb had gotten DSV to deliver my card. They contacted me on 2nd July and said that my card will be delivered in 3 to 5 working days. The time passes by and no card is delivered. I contact fnb and they state that card was handed over to DSV so I need to speak to someone from DSV. I mailed them on 11th July asking where is my card and was mailed back on 13th July. The email read as your parcel was on route on 06th July but the driver said that you cancelled the order so confirm if this is correct. I rep**** stating I had not been in contact with any one from DSV so from whom was the info obtained and when can I expect delivery? She then stated it was what she was told by the driver. So she requested for the card to be sent out again. I had still thanked the lady helping me and once again asked when can I expect my card and this time no response. Today is 4 days later since my last email. Its my first time using DSV and I have never seen such pathetic service. One or two days late and I will understand but now it's ridiculous.
