Getmore cancellation difficulties

I called the on January 26 to cancel my subscription, they said it a 30 day notice so I will be Charged on February I was fine with that. I called them on 16 March 2022 as the have charged me after calling in January the call urgent just said he'll get back to me of which he never did. I called again on the 17th of March 2022 that lady said she will escalate the matter of which I doubt she did as I saw my April statement I still charged for Getmore services. for 2 months they have been charging me now after cancellation.
