Worst service EVER!!!!

For over 2 months now Telkom has been charging me for a device and sim I returned to them on the same day the courier delivered it to me becos I had cancelled the contract before delivery. Every time I call in to log a call I am always told they are escalating the matter (I'm starting to doubt there is even an Escalations department in that ****hole of a company) ... I've even been ranting on social media and their account managers also tell me they are escalating the matter. They keep taking money from my account and are refusing to remove the device off my account and yet they can clearly see I'm not using the data on the sim and I have been sending them receipts from the courier company proofing that the device was returned to their warehouse.

I have cried out of frustration and anger so many times when I see them debiting money from my bank account and I end up falling short on my budget bcos i do not have money for them to just take and keep for god knows how long! I'm tired of hearing the song "we're escalating your case" it's making me mad! I just need someone in this so called Escalations department to call me and tell me they have terminated the phone off my account and when am getting my money back!
