Unhappy client!!!!!!

Extremely frustrated with FNB. I have been calling their fnb connect service number every week since february to no assistance. I bought a smartphone contract via fnb shop. The devices was hijacked in transit with the courier company. They sent a replacement phone which i recieved

Now problem is, the hijacked device is still on my profile and i am paying for it. Also, the replacement device(same as the one i intially bought) is now more expensive than what i signed up for. I am paying for 2 devices instead of 1.

I have contacted fnb several times to no assistance. I called, I tried their secure chat and NOTHING!
