Poor service and admin

To whom concerned On the 16th of February 2021 I dialed your helpline nr 084145 and spoke to a lady called Precious to cancel my contract which had reached the end of the contract period. During a lengthy call she recorded all my personal and bank details to cancel the contract and the debit order. She confirmed telephonically that the termination process was recorded in your system. My contract details were as follows Contract nr *** Cell nr *** Starting date 7/01/2019 and expiring on the 7/01/2021. She informed me that the contract would be terminated after the applicable notice period and it was subsequently confirmed by SMS. Please let me know what the repeated payment request emails are for>
