Got very high bill and Autopage passed the buck

My account average R470 per month. This month I got a R3750 account and query it. Tahir just respond to me that I must have a virus on my contract computer. Just that. No inclination to report an investigation or suggestions that there might be a problem at accounts. I know I do not have a virus because my computer is protected. Now I must pay more money for an IT company to check my contract computer? It is only me and me alone working on my computer - nobody else. While he was \busy"with me the shop's phone ran twice and he answered it so his attention was distracted from me with my problem sitting in front of him. When the phone rang again I answered it and said that Tahir is busy with a client and took a message. The message from that person was the same as my problem. The guy received a very high bill for the month and he does not know why?<br> I am very disappointed. I am a client since 1980 and expected better client service that this. I asked him if there is a way to get to the root of this problem and he said he can log a investigation. If I did not asked what we can do he would have sent me away to a IT company. I expect more that this bad attitude."""
