Disgusted

I have been a loyal customer with Telkom for many years now. I reported that my internet was not working properly. All my lights on my router are on and connected but I can't connect. A Telkom technician comes to my premises on Sunday 15th February. He spent an hr standing and staring at the router calling his collegue on his mobile phone unsure what the problem is. He makes ME call Telkom myself while standing and staring at the router. He then says he will come back in an hour. 5hrs later he appears at my gate. No one is home, he calls me saying he will come back tomorrow (16th) which is today and time is 17:07!!!! He hasn't arrived. I WILL CANCEL MY ADSL LINE if this problem isn't sorted out!!!!!
