Waiting over a month for a replacement

R 27 000 laptop has been faulty since the 24th December and as of today the 27 January Dell are unable to advise when we will receive a warranty replacement, I have not been able to work for a solid month now. If you are so lucky as to get through to them in some cases holding as long as an hour, we are advised we are unable to advise when your replacement will be dispatched. Cant believe that a company service is so bad that they are unable to offer a replacement for a warranty for over a month. !!!!!!
