MAKRO - don't bother to reply - no after sales service on a faulty defy stove

Following my complaint this morning - I have still not heard from Makro - about 2 things - a faulty Defy stove that we purchased which we have not been able to get repaired. And NUMEROUS requests for an invoice for a 2nd stove we purchased that must be made out to our company name. I write emails to the following email addresses and not one person responds: Makro Care E-Mail ********** Makro Care E-Mail ********** Makro ********** ********** Its a simple request - send me a Tax invoice for the purchase we made online. Send someone to fix a faulty Defy stove that was purchased in January.
