unsatisfactory service

we have returned a product, it was an invertor, we had it over 30 days, as there was no load shedding to test the product to its capabilities, and when it was load shedding we found that the product was inferior for the usage we needed. Upon emailing, as you cannot speak to a human at Take a lot, Niaz or Nihaam told us we could get a refund. Following up today, as the status for return is concluded, Lunga has now emailed and said the product would be sent back to us. We DO NOT want the product back! Can a manger from Take a lot call us, this emailing thing is not working. Robin Mc Gregor ***
