Bad service

I bought an air fryer online on the 20th November 2021. Waited 6 days for delivery and the wrong item was delivered. I emailed customer service to no avail. I then called the Monday and received a reference number and was told someone would call me within 72 hours, NOBODY called. I then called again and was told they have escalated my query. BUT, still no email or call. In the end I called head office to escalate it myself. Within a short period of time, a manager called me and assisted and the wrong air fryer was collected. BUT, it's the 9th December now and still no communications from the online team as to when I will receive my actual product. Again I had to call the manager, and was then told the product is not out of stock and I can only expect it somewhere end of December!!! !!! I specifically bought ONLINE to prevent ques etc and EARLY to prevent stock issues!! I bought it as a gift for someone now they won't have it in time!!! Just one more company to add to the "bad/terrible/ non-existent customer service list.
