iStore online - Atrocious service

Istore online service is atrocious... After finding a deal I was interested in on Friday 20 Aug via the Istore website, I opted to upgrade one of my Vodacom contracts. The response from the consultant Nompumelelo was fairly quick, where they asked for confirmation and screenshots of the deal I was looking to upgrade too on Saturday 21 Aug. On Monday 23 Aug, around midday, I emailed Nompumelelo asking for feedback and for timelines of when I would be receiving the device i had chosen. No response from anyone on Monday... On Tuesday 24 Aug at 19h53, I received an email from Nompumelelo, stating that the deal was no longer available... I also then received an automated email from the website stating that they were unable to reach me (no one tried calling me? I had been speaking to them via mail just fine??) and that they were unable to proceed with my application.. I immediately emailed Nompumelelo, and asked what was going on? No one had attempted to contact me? and the deal was available on the website when I app****? I also stated to Nompumelelo, that I sent screenshots from the website, thus proving that the deal was available at the time of my application. Nompumelelo then responded at 19h57, stating that she would provide feedback the next day. I again had to email asking for feedback from Nompumelelo on 25 Aug... Nompumelelo sent me an email trail that included senior management. In summary, the mail trail stated that the deal did not exist. I then emailed Nompumelelo asking when the deal would then be made available for my upgrade, as I still want the deal... Nompumelelo then responded that they were still waiting for feedback, and requested for timelines of when I would be getting feedback. No response received... I then once again tried to reach out on 26 Aug, emailing Nompumelelo and their Seniors, asking for feedback... No response... How can it take a week for a simple upgrade... Just to atleast provide feedback or timelines of when we can expect this to be resolved... At this rate, the new Ipad will be released and I still wont have a resolution on this current one... I want the deal as it was advertised on their website a week ago.. It is not available on their website anymore, but it was when I app****...
