Bad Service Makro Cornubia

We bought a set of speakers. Took it home, fitted in on. It was not sounding right. Packed it back in the box. Took it back to Makro. The supplier in front of them said take it back and send it to me for inspection, however, please give the customer a replacement as he will sort out the damage speakers. The rude lady Wendy Alexander said NO, you send the new unit for the customer. He was rude and refused to assist. Why would anyone want to spend there money at a store were people are rude and unhelpful? The supplier clearly said to lady to change it for the customer, Which part of that did she not understand? The height of incompetence and bad customer service!!!!
