Bad out of box failure support

We bought 4 new Dell Notebooks for a client and had 2 that where complete out of box failures - with keyboards that didn't work etc. Unlike every other supplier in South Africa, Dell do not abide by South Africa Consumer laws which say we are entitled to an exchange. No they want you to log a call and they will send a part out next day (try 3 days later we get a phone call instead) Needless to say after 3 days of no part, we get a call to say sorry there is not stock for 2 months?? This is a brand new notebook??? After throwing my toys I am told I can get a credit and they will collect the notebook. Eventually they do collect it but here is the next catch.... You have to wait 21 days before they will credit you. What can we do? You have to take their ****?<br> <br> So after waiting patiently for 21 \working"days what happens????? No credit - Now there is absolute confusion between Dell and their distributor Drive Control about the incident"
