Horrible Service Communication

I have sent numerous e mails to Vox cancellationsto cancel Web Connect Order and UPS Device. First e mail was 12 October 2023 thereafter 4 e mails and since then not one single reply from them, they just carried on with the order, the UPS arrived with Courier and i refused to accept it and the courier returned it. Thereafter e mails were received from Vox to accept Debi Check Mandate.... which i DID NOT ACCEPT OR AUTHERISE. Again i sent e mails to vox to cancel the orders as i told them from the beginning of the order while it was still in proccess to CANCEL IT, as i am no longer interested in WebConnect or a UPS. No response ! Yet despite not authorising a debi check mandate Vox tries to debit my bank account 3 times. Vox... i have all the e mail communication proof that i cancelled this order way in time before finalising it.... If you do not correct this and carry on with this i will go to ombudsman and Consumer services and report this. CANCEL THAT ORDER AS I HAVE SAID SINCE 10 OCTOBER THAT I AM NO LONGER INTERESTED.
