********** debit orders

Do not have a contract with this company. They keep debiting my account and I have been in contact with a number of their employees to no avail (Diane Francis and Erna Halliday). They did this for a few months at the beginning of 2020, and subsequently stopped after a constant back and forth, and realising that whatever contract existed was **********. They re-initiated these again in December. Potential modus operandi to up their revenues?
