bad service

over week ago my account got charge for an amount i did not approve of, i called discovery bank, the immediately block card and i completed form for refund, a lady from bank called and said they will deliver my card on friday, i requested a special delivery for wednesday as hubby has heart failure and i needed to be in cape town on thursday morning early, she said she will organise this with dsv couriers, well i wasted over R400 on prepaid airtime calling bank and dsv that wednesday for my card delivery and this was not done, i had to loan money from neighbour to help me with petrol and cash, thursday i emailed dsv and requested for my card to be delivered and this was not done, i had no more airtime to call back, well friday came and my card still has not been delivered, i was now being anxious as i had to buy medication and food for hubby as he is not well, after a few more calls to bank and courier, no delivery was done, its monday now at 5pm and dsv called me, they will deliver my card today, nothing has been delivered, im furious and upset at this whole setup, and especially wasted unnecessary funds on calls, times are hard and i need to watch what i spend money on.......
