sewing machine repair

I handed in an Empisal sewing machine still under guarantee for repair on 9 December. The machine was in 'as new' visual condition. The timing mechanism was the problem. On 20 January I emailed Makro to complain of the disgusting dirty condition in which the machine was returned and that various parts were missing. This was confirmed with various other emails to Makro Care and visits to Makro Milnerton. The missing parts were: the extension table and the ****l pins (essential parts of the machine). I don't believe that it my machine that was returned to me, as the switch selector dial was damaged with strange ingrained white marks as through something stuck to it had been torn off. I returned the machine to Makro Milnerton and spoke on the phone to Louis Karpas who said he would look at the tapes to check the missing parts where there when I handed the machine in. The person at Makro who checked back in, also pointed out that the switch selector dial was loose – an added fault. Since then I've had numerous mails to Makro. My replies from Makro have been that they are sending my complaint to the relevant department – the last one on 4 March asked how I would rate the support I received. I answered zero and explained. I haven't had any reply since. They still have my machine. Louis Karpas' direct line to him that he gave me, links to the 0800 call centre. Of six calls to it, I only got an operator once who couldn't help me, but said she would send an email to Milnerton Makro customer care to phone me. I've received no calls. No satisfaction. No sewing machine
