Bad Service from On Air TV

On Air TV sales contacted us with an offer for DSTV Explora package which we accepted. Same day follow up with emails and sms. We arranged delivery for 9th July. No delivery and we had to ask someone to put their whole day aside to wait for delivery. Called On Air on 10th July at around 8:15am and they advised would follow up with Ram hand to hand couriers and get back to me. Now 16h41 and no feedback. I called Ram and advised I had not received my delivery on the 9th, they advised it was scheduled for today, called them again and now they tell me they have been advised to hold all On Air TV deliveries until the 15th. We have not been contacted by On Air regarding this as would not accept anyway. You get the sale all good but after sales sucks. What is going on.
