Terrible returns policies

I bought an airbed from Makro Springfield and had an issue with it, we were living in Johannesburg for a while so I returned it at Struben Valley Johannesburg, they took more than two weeks to respond and by the time we returned to Durban they sent SMS stating that we need to receive our credit at that branch. I went back to Springfield and they said that we have to receive the credit at the branch where it was returned. How is this one umbrella running under the same name if I cannot receive the credit at the Springfield branch in Durban? I also had an issue with my Garmin that I bought where it wasn't picking up satellite properly, when I need to take a turn it would tell me after I passed the turn, I took it in as well, they booked it in and I really can't imagine the outcome of this problem. I am expecting a ",nothing is wrong with this product answer" and supposed to pick up the faulty Garmin and continue missing turns causing accidents on the road. I am seriously dissatisfied with Makro, no wonder the complaints they have. Browse Makro, compare complaints vs compliments, absolutely shocking and regret doing business at this chain!!!!
