Whirlpool in South Africa - We're waiting for a resolution!

Purchased a new Whirlpool washing machine from Makro. Machine does not use enough water to clean clothing. This machine could not be registered on website - no one at Whirlpool could sort out the registration of the machine. Queried with Service ********** on 20 August. Since then 29 emails have been exchanged. Whirlpool technician came on site and confirmed that the machine was not working properly. Was promised a store credit on 13 September. Have emailed requesting update on store credit. no reply. Various names on the Whirlpool end of ********** are: Ederies, Saleem, Shamielah, Mthunzi. Please will Whirlpool resolve this issue!
