Worst Service Provider

The service received from Telkom! I have called 4 times to amend/stop my debit order in the last 4 months yet the people employed here are so *********** and cant do their jobs. I was told i could stop my debit order and pay directly and today after 4 months i was advised that this could not be done. After speaking to 3 people and for almost minutes i managed to speak to someone at billing who instead of handling my query proceeded to put me through to cancel my contract very quickly. I then start giving her my details to change my debit order and she then proceeds to cut me off ... now i must start and call the whole process. This is the worst service provider!!!!!!!!!
