TAKEALOT........ OF TIME TO DELIVER THE WRONG ITEMS... AND THEN IGNORE YOU...

We ordered a laptop battery online on the 1st of October 2018. Delivery was scheduled for the 3rd of October 2018. What arrived on the 3rd was a computer mouse and not a battery as ordered. I logged a return on the afternoon of the 3rd and was told that the issue would be resolved within 24 hours and I'd have the right order delivered. Nothing happened. The return was logged again on the 4th and still nothing. we complained on the 5th and were told that the incorrect package would be collected on the 8th and the correct item delivered at the same time. Today is the 9th. The wrong item has been collected, but it's been a week and I still don't have what I ordered. The call centre is useless - nobody knows their asses from their elbows and no Managers are available to assist. NOT HAPPY...
