Wrong Device Delivered And They Are Refusing Returns

I purchased a device from BLC after being referred by Vodacom. The device I agreed to was a ZTE Axon 10 Pro 5G at R329 per month. But the phone delivered is a ZTE Blade V7 Lite MTN, which is way cheaper than the device I agreed to.

I called the call center and I spoke to Michael Phabete (His manager is Ruph Mnisi). When I told him I got the wrong device, he told me I cannot change the device meaning I am supposed to be stuck with this phone and pay for it when it is a phone that costs less than 30% of what I ordered. From the voice call, he sounded like he knew that I did get a wrong device but there's something ***** going on which they don't want to say. I would not advice anyone to use this company because now they are refusing for me to return the device which was delivered 30 minutes ago.

This is horrible **** company.
