FNB Smart Devices Call Centre

I ordered a smart device (laptop) from FNB, they delivered the device. The device delivered did not have the same specification as it was advertised on there website. I phoned FNB Smart Devices and after explaining this to 5 people they cut me off, phoned again got cut off again, 4 times I got cut off. I asked to speak to the manager, they transfered me to Michelle which is apparently a team leader at FNB Smart Devices. I explained the matter to her and she said she will get back to me the same day. Never did, phoned today, got cut off again. Phoned my Private banker, she cant help me I must phone Smart Devices. Why am I a private client at FNB? For What? The service is so bad. I have spent the last 2 days 4 hours on the phone trying to sort this out. Looks like FNB will be loosing me as a client.
