Pathetic after sales service.

I ordered a WiFi router about a month ago from Telkom. A week ago I received a SMS advising me that my router was going to be delivered on that day. I should pls have my ID and utility bills on hand. I postponed my outing for that day so I would be home for the delivery. No delivery came. No following from them. Phoned them numerous times and was promised immediate delivery but still nothing. My family work from home and without a good working router it is becoming very difficult. They asked me to check with skynet courier about my delivery. Tried many times but skynet just does not answer their phones.
