Useless Telkom

I went to acquire an adsl line from Telkom on the 2nd February 2015, on the 9th February they sent me a sms stating I should pay a R700 installation deposit that I paid on 10 February. For a month haven't received a sms or phone call from them. I got an invoice from them on Monday stating that I have R 700 credit. I went to the store on Tuesday (10/03) and then only my line was tasked to a technician. Hopefully it gets installed on the date they said, the 4th of April. I guess the point I am trying to get across is that the service we get from this place and the money we pay them should deserve some competence on their part. ABSOLUTELY USELESS!!
