Makro pathetic after sales support.

We bought a tablet from the makro store in carnival to start off there was no one there that could assist us they had a whole bunch of sales people but the only person that could help us with any info on the tablets was behind the counter doing payments. I bought the macer tablet and got home downloaded games and then when we tried to turn up the sound the sound button didn't want to work. We took it back the very next day before 9am and was told no they can't refund us or exchange it coz it's an electronic item they have to send it to the provider to fix it first which is against the consumer act. This was not disclosed before purchasing the item and any other store in South africa you can return the item within 7 days regardless of the issue for a full refund. Makro would rather inconvenience the clients and punish the clients for defective items. I'm still waiting for feedback from makro on the item we took in. But yet still nothing. There is a small plsection on the invoice which is only pointed out to you once you return the item. Pathetic service or after sale support from makro
