Telkom account suspended for NO REASON

I took a Telkom data contract of 10GB for R139 p/m through Mondo on the 22nd of May 2019. The device and the sim were delivered on the 29th May 2019 after an activation fee of R99 was deducted from my account on the 25th May 2019. The simcard was then activated 2days after I received it and I was able to use my device with data for less than a week. Then all of a sudden I could not connect anymore, I left it for about 2days thinking that there were network issues because Telkom can lose network at times for a long period, on the 3rd day which was the 8th of June 2019 I called Telkom and was assisted by a person called Katlego Phuthi who then informed me that my account was suspended die to none payment, I fought with the person because my next payment due is would be on the 25th of June 2019 and it made no sense why my account was suspended. The person then logged an escalation call to the collections department they said they could not help me in any way but log the call for me, I then waited for a further 4 days for the issue to be sorted and still nothing changed. I called again on the 12th of June and spoke to a guy called Thokozani Mthethwa explaining my story and as usual the best he could was to log a call again to the same department as the previous person I spoke to, I told the guy that I would cancel my contract because I am very unhappy and he went on to tell me about the cancellation fees that I would incur and advised me to wait for at least +/_ 5hours, I told him that I would give Telkom at least until Saturday of which I did. Today is the 15th of June and I still have not been sorted out, I just spoke to another person now called Nomzamo and AGAIN I could not be assisted but just told that a call will be logged to the collections department, when I demanded to be given the number for the collections department I was told that they don't have a number I can call and that I should communicate with the USELESS call centre agents. My next step is to take the legal route because I cannot be this UNHAPPY and be expected to pay come month end!
