Disorganised business - watch out for deals they do not want to honour

On 19 October (note, the purchase date in my first review was incorrect), I purchased a new Macbook Air M1 for the stated price of R15999 from INCREDIBLE CONNECTION (IC)at the Tygervalley branch in Cape Town. The tag next to the said laptop stated that there was a saving of R1000 and then under that was written 'R500 voucher'. I took a screenshot. The sales staff - at least 3 of them- explained that I would get the voucher after purchase and could spend it on an item in the store. I asked for my voucher once I had paid and then was told the voucher would arrive by email in about a week or more. I subsequently got an email from JDG buy&get at Incredible Connection informing me that I needed to send a copy of my ID, which I did. I then got another email informing me: 'Thank you for registering your recent purchase, unfortunately the product you purchased does not qualify as part of the promotion for the Buy and Get voucher.' I rep**** that it is unacceptable and also sent a screenshot of the deal. I also sent a review to Hello Peter on 25 October. On 30 October, I received a curt reply 'Noted your voucher will be issued latest tomorrow.' I received it on 01 November. It is now 7 weeks later, and after contacting the IC customer support line twice - where they stated that the balance on the voucher showed as R1000 (but on my side, it showed a zero balance)I still cannot use the voucher. On 04 November, I received am email from a customer service agent, with a photo attached showing proof that the voucher balance is R1000, so I mailed her with a photo showing proof that there is a zero balance on my side. She told me she would come back to me. I am waiting to hear from her. I am extremely disappointed and would not recommend IC.
