DISMAL SERVICE! NO CALLS! NO FEEDBACK! NOTHING BUT USELESS PROMISES!!!!

I was due for an upgrade which I opted for. The consultant took me through the application where a new device, package and colour was chosen. This was in April. Two weeks after receiving now feedback or phone, I called and was told that the phone has been discontinued. No one told me anything prior to the call. I chose a new phone. This was then also discontinued. Again no one called or mentioned anything. I had to phone in. Almost a month later I chose a new phone. The Samsung A72 in BLUE. A week later still no phone delivered. I again called in and was advised it's on back order and to wait a week. Called in a week later and still on back order. Last week only was the device delivered but guess what. It was the wrong colour. I have called, emailed and again called numerous times to have it picked up and still nothing! Each time I need to call in for assistance and feedback. Are they so busy that a call can't work? Why do I need to keep calling? I refuse to pay for this when I have tried correcting this numerous times. SORT THIS OUT!!!!!!!!! DELIVER THE RIGHT DEVICE IN THE RIGHT COLOUR!!!!!! PICK UP THIS WRONG ONE!!!!!!!
