non delivery of DSTV unit

It has taken nearly 3 weeks of toing and froing with the supplier, after been promised that delivery of my dstv decoder upgrade would take place within 5 working day, to try and get my new decoder delivered. Don't expect that the required documentation necessary will be made known to you on the first attempt! After three attempts the unit could still not be delivered because the telesales person forgot to inform again what documents would be required to be handed over with delivery. In frustration I decided to cancel the order fearing that if this is how On Air TV conducts their business can you just image the atrocious aftercare service you could expect
