Poor Service from FNB

On the 11/11/15, I had contacted FNB requesting why my ebucks for online purchases made in July had not been credited to me, I had received a reply from FNB stating that I will be credited with the ebucks between 4-10 December 2015, this is strange that I made the purchases in July and will only be credited in December, but then the ebucks that was credited to me was less then what I purchased for, I had contacted FNB again and was told that ebucks for online purchases on a platinum credit card is R5000, so I rep**** and it took over a week for a response, I had then complained on twitter on 21 November 2015 my query was then escalated and i received a ref 818314 on 24/11/15, after numerous reminders for a response, i finally received a call from FNB on 18 Dec stating that I was credited with the ebucks on 1 Sept and part in Dec, I received no ebucks in Sept, I had then checked and I received ebucks on 09/01/15 for a different purchase (its not 01/09 its 09/01 (9 Jan)). She then emailed an apology and advised I received the right ebucks, however ebucks website states that its capped at R5000 at reward rate and thereafter 0.6%. This also took more then a month and still waiting...
