Very poor communication

After countless calls to telkom and waiting on the line for almost an hour at a time, and sending an e mail 2 about 3 different e addresses found online and chatting to them online I finally got hold of Telkom today. All I need to do is change my banking details. for the past 3 months I havn't been paying my Wifi due to not getting hold of them. Now because of the rejected payment on my previous account I should pay a rejection fee of R250 where my account is R200 a month. This is insane. I tried contacting Telkom a number of time without any luck, is this my fault that the account is in arrears now and there is a rejection fee of the unacceptable amount of R250. This is on a contract so is there any way I can cancel my services ahead of time? I do not want to know or do bussines with Telkom ever again. please feel free to contact me if that is going to happen because communication is not one of Telkom's strong points. Cell: ********** 036
