Bad service and not concerned about client

I've been waiting for a dilivery from Discovery Bank from them for over 3 months now. Every time they have to deliver its invalid reasons after the next. Their service is poor and I do not recommend it as I've been taken from Pillar to post with no assistance. I've lost on potential investors as the card I was waiting for was for starting a small business but with failure of them delivering I have to start over. I'm very disappointed with the level of service of such a big courier company and will not use it for any deliveries going forward
