Poor service and Double payment on contracts

Upon upgrade of satellite dish/contract on 2nd Dec 2021, debit orders were deducted from my account for both the old contract and new contract for the month of Dec 2021 (therefore paying for the old contract still after the upgrade). The old capped debit order has been deducted end Nov 2021 that covers the month of Dec, as well as a pro-rated debit order for the new uncapped contract also covering Dec 2021. Upon follow-up I was informed that they could not cancel the previous contract end Nov 2021 therefore I was billed for one last payment during Dec 2021 on the old package (although this satellite dish was disconnected on 2nd Dec 2021 with the installation of the new satellite dish). I WAS GIVEN NO OPTION OR PROVIDED COMMUNICATION to then rather await the installation of the new satellite dish at a later stage towards end Dec or even early Jan 2022 instead to avoid this double payment on the 2 relevant contracts. I believe I should have been upfront of this rather to have options. Subsequent follow-ups asking for a refund have all since ALL been ignored.
