Irritated, disguised and annoyed with Telkom

In July I phoned Telkom and enquired about the wireless 10g LTD router that they are advertising. I was told that they do have and that I qualify for one. So I placed the order and the router was delivered to me on the 26th July. 3 months went pass and I saw that Telkom had not debited my account and I was unable to get hold of them via the 10213 number. In October a lady phoned from Telkom stating that my account was in arrear and advised me to make a payment of R540.00 (this I did on the 16th October) and the balance of R269.00 would be debited from my account. The lady also explained that each time they did a debit order that it came back as insufficient funds, I explained to the lady that Telkom has never debited my account in the last 3 months. On the 26th October my bank account was debited with R807.00, and when I queried this I was told that they had sent me the incorrect router and therefore the price was different, I was also told that the package that I original asked for is a handheld unit and was not suitable for what I wanted it for. I then stated that I would accept the package that they sent me and that the price would now be R269.00 per month. I was then told by the accounts department after being on the phone already more than an hour with the previous gentlemen that they would refund me the amount of R540.00 as they could see that my account was definitely in credit with Telkom. When I asked how long this would take I was told no longer than 72 hours. Well it has been 3 weeks and I'm still waiting for my refund. Yesterday 15th November I received my statement from Telkom and it shows that I owe then R738.70..... I sent Telkom a message and a gentlemen by the name of Kasendrin contact me and explained that he was actually from the new applications department and that he would sent the finance department and email requesting that somebody contact me regarding my account. I told Kasendrin that I am so unhappy with Telkom and that I want to cancel my debit order with immediate effect as I can see that my account will be debited with R738.70. He said that he understood my frustration but he said that somebody will definitely contact me. Well its been almost 5 hours and still nobody has phoned me regarding this. I also see on my statement that I'm being charged a rejection fee of R538.00 and a monthly subscription & usage amount of R405.00. This is yet again totally incorrect. I am so irritated, disguised and annoyed with Telkom at this moment and I will never recommend them to anybody. I don't even feel that they should be in business
