Incredible Connection ignores complaints

To cut a very long story short, after purchasing a netbook at the full retail price of ZAR 3,999.00 1 month prior, there was a problem with the charging mechanism, I feel it is the supplier's problem but of course they said I damaged it. My issue however is that they are trying to charge me ZAR 5,500.00 to repair the computer which I had bought 1 month prior for ZAR 3,999.00!. What a *******. Their website gives an email address for complaints - no response. I phoned and left a message - no response. 24 Hours later I escalated to the manager - no response. Another 24 hours later I escalated to the CEO - no response. So after almost a month sitting with Incredible Connection I still don't have my brand new computer back and if I want it repaired I have to dish out ZAR 5,500.00. The branch manager that I took it to is going to try get a second quote on the repair but its insane that they are even trying to charge me for the repair, let alone trying to totally rip me off. After a week of trying to get replies, I am now fed up. I see this company responds to Hello Peter complaints but this will likely be ignored too.
