FNB GOLD DEVICE LACK OF CUSTOMER DELIVERY

I app**** for the fnb gold device and realized I wasn't happy with it. I took it back within 7 days period, but because of the public holidays during that time Maponya mall branch couldn't take it in as their system didn't allow them to. I then called fnb call center and an arrangement was made for the courier company to collect. The courier company (RAM) collected it on the 5th April 2016 and till this day no response regarding the way forward, as I need to receive the R1000 I paid upfront back. I have been wasting my airtime for the past 3 weeks and each time I was told they sending an email for the matter to get escalated....till this day! I am so disappointed and angry at this and I want my money.
