Dissatisfaction in service - Discovery Miles not allocated

In June all Discovery members received an email advising how they can earn Discovery Miles for the month of June. I especially asked my employer to change my account details to Discovery and my salary was paid in my Discovery Bank account in June in order to receiveDiscoverymiles as per the email. I also used my Discovery card and paid for a transaction to ghe value of the amount stated in the email. July came and no miles was allocated for the above....then I logged a query with Discovery via Twitter and the requested I forward the email to them which was sent in June, I also explained the above to them via email to *** which I was requested to do. I have been following up with Discovery since 2 July and I am still waiting on the miles to be allocated. I keep getting holding responses but no proper feedback. I am disgusted and disappointed in the service. I thought very highly of the bank before but now I'm not sure a simple request is taking over 2 weeks to be resolved.
