Extremely disappointed with Jet Bluff

I bought a phone from Jet using my TFG account. I was called 3 days after to return the phone because they gave me a wrong one. The phone that they gave me was sim locked and I requested for a phone that wasn’t. They told me that they insured a wrong phone so basically I am paying for insurance yet the phone that I took is not covered. I told them that I will return the phone however the phone has a screen protector now they must make sure that the phone they are going to replace it with will also have since I paid R200 for it at Vodacom I even showed the lady the receipt. She said she will get back to me. I got a call from their branch manager requesting that I bring the box because it does not match with the phone that I have with me and it will cause issues for them because their stock will not balance….. she said I will have to keep the phone that I have because they will not pay for a new screen protector however they will cancel the insurance and refund my account for the premiums I’ve paid. Till date I see that I am still being charged for the device insurance, they have not cancelled it and refunded the funds that I have paid. I have not heard from any of the Jet members. I bought the device on the 30th of the 9th month last year. I have receipts and pictures of the box and back of the phone the MIE does not match. The phone that I have is sim locked I cannot use another sim on it. When I recharge on that sim the airtime disappears 🤦🏽♀️
