Worst after sale service time and time again

Tried to return a 1 month old faulty hoover vacuum cleaner. Called and spoke to Lucas who after advised me to bring in the vacuum and he will make a decision to exchange as I cannot go with out a vaccum due to asmathic health reasons. Lucas and Xuma then refused to assist and my only option is to book it on and wait 21 day. They couldn't care less of the health issues and necessity of having a vacuum daily. 1month old and the worst possible after sales services as Lucas said they just sell the product and they are not the supplier. 3rd vacuum returned in the past 18 months. Makro will take your money but make you wait when they supply faulty items. I will never support Makro going forward and I will take this up with the CPA as the item is under 6 months old. Most unhelpful retailer in South Africa
