After-sales service pathetic

For the second time in less than a year I had to return a defective item purchased from New World. On both occasions the after-sales service was virtually non-existent. On 25 February 2016 I returned a defective Philips iPod Docking station. I was promised that I would be given feedback within four days. After hearing nothing from New World, I contacted them every week, always hearing that there is no feedback yet, but that they would contact Philips and call me back. Needless to say, I never received a single call from New World. Eventually I replaced the item myself. A week ago, after calling again, I was told that Philips could not repair the item and that it would be replaced. However, I don't want two docking stations. After explaining to the staff that I was forced to buy a new docking station because New World never returned any calls nor did they seem to make an effort to get a reply from Philips, I was told that it was against their policy to refund the cost of an item returned under warranty. In fact, I was told that it had been my own choice to replace the item (after almost three months of not getting any response from New World!) New World has lost another customer, merely because they lack any respect for their clients once an item has been purchased. I had the same experience with Jubra headphones (for joggers) which started malfunctioning during the warranty time. In desperation I called Jubra, after walking into a wall at New World time and again. Jubra offered to replace the headphones with a much better model, at no cost, saying to me that I must just forget about working through New World. It serves no purpose buying an item from New World at a reasonable price when the after-sales service is non-existent or as pathetic as I have experienced it. Next time I will shop somewhere else.
