Makro Extended Warranty - More headache than service

I purchased a Samsung TV from Makro and took out an extended warranty on the TV. The TV broke down and I contacted the National Call Centre to report it and to activate the extended warranty.

The repairmen came out to assess the repairs. They advised that it was not repairable and that I would then get a refund voucher from the Extended Warranty Department so that I can replace the TV.

The Extended Warranty Department contacted me and advised that they would send me the voucher via SMS. To date I have not received the voucher.

I again called the National Call Centre to get the number of the Extended Warranty Department. They advised that they don't have the number.

So here I sit a month later with no TV and no way to contact the people that I need to speak to to resolve the problem with the voucher.
