MorClick - Impossible to do business with them

I received two quotations from MorClick for the installation of Satellite WiFi. The quotation numbers are Q28643 and Q28395. I call their customer services to inform them that I am going to relocate from Manguzi KZN to Potchefstroom NW Province and I don't need the installation anymore. Everytime the operator said someone would call me back, which never happened. The company is just continuing sending me bills as if there are contracts concluded between them and myself. The haven't installed anything, but they submitted to me invoices indicating travel cost, installation cost, monthly fee etc. I electronically informed their e-acceptance, customer care and billing departments that I did not accept the quotations. They are keeping ignoring me an informed me the amounts will be debited on my account on 27 Dec 2022. I therefore withdrew all my funds from my account, because there is just no other way of stopping them.
