Request to cancel Email address not followed through

Two months back I requested via Facebook that my alias email address be cancelled and removed. I was advised by the consultant (all correspondence via Facebook) that the account would be closed at the end of August. It is now 5 September 2018. To date I am still receiving emails to my email that I requested to be cancelled. Numerous correspondence via Facebook over the past two days and still the account is active - I in fact received emails this evening to the email address. Clearly someone is not doing there job at Mweb. I need this sorted out. I should only have one primary email and only being billed for that one account not two. Please resolve this issue immediately. You have had almost two months in which to schedule the cancellation and it was confirmed all in writing.
