NON-EXISTANT CUSTOMER SERVICE!

To F.N.B.: - Why,may I ask,do you offer a Customer Call-Back Request Form on your website,when you clearly have absolutely no intention of responding to ANY of those requests whatsoever??? I have been wasting my time filling out that form for 2 years now,& I'm still waiting for a single reply.If you are going to provide the customer with such a forum,then please have the decency to respond to those requests,instead of ignoring ALL of them,ALL the time.I find your customer service to be quite appalling,not to mention,non-existant.My complaint today:On 18/11/2015,I received an E-Mail from you,offering me a 20% off Discount Voucher to shop at ZANDO,valid till 04/12/2015.The voucher stated that the discount will be automatically app**** when paying with my F.N.B. Gold Credit Card.Well that's exactly what I did,& guess what? - No Discount! - My Order went off for the full purchase price,& the full price has been charged to my Credit Card.Please let me know whether you have any intention of honouring the voucher.If not,then I will be immediately returning the goods for a full refund. - Thank You!
