Been a loyal customer but DSTV are not a loyal service provider

If there was a minus star I would have rather used that, I have signed up for Pricelock in March 2019, but since last month my premium has gone up to R1326.90 I phoned last month and was told an agent will contact me within 48hr to rectify the problem, this month I got an sms on Monday 30 Sept 2019 @ 16:10 to inform me that the Debit order of R1326.90 will go off on the 3rd of October, so I phoned DSTV and spoke to Sandile Ref ***6/02 to tell him DSTV is in breach of contract and if this Debit order is going off I take it as that and will cancel my DSTV with immediate effect and he assured me the call is recorded and an agent will phone me to sort the matter out before the debit order, that did not happen, the R1326.90 debit order went off again, so DSTV is in breach of contract and I demand that all monies and cost must be credited to my bank account and my contract terminated
