Defy service

I have a very nice Defy vacuum cleaner but it has a flimsy charging cable which has been a problem and I have tried numerous options to find a replacement. I emailed Defy customer support on about 8 April (or earlier). On 15 April I called their support number and was told a customer care agent would contact me. I am writing this on 24 April - to date I have not received a reply to either of my support requests. Based on this I will never purchase a Defy product again.
