Irregular charges

I signed up for a month to month contract in 2015. I left south Africa in August last year and requested a cancellation. I was told that I had signed a long term contract - I would never have signed a contract like that. When asked Telkom were unable to find evidence of my contract. Since then I have been charged more than R4000 in irregular fees, with amounts coming off my account some months to the value of 1800, while others are only 299. I have complained and contacted Telkom numerous times without any resolution at all.

Stay away from this *****ed company, they are a bunch of *******.
