Automatic renewal of MS Office 365 subscription through Mweb.

I have a Microsoft Office 365 subscription through Mweb. Last year (2022) I received a notice to renew my subscription, which I did, only to find out that it had already been renewed . I could not cancel, as the penalty was close to a full year's subscription. So I paid for 2 subscriptions the whole year. This year (2023), wanting to avoid a recurrence of the same, I phoned on 4 April ( the last day of one of the subscriptions), to cancel it . I was assured that I would only have to pay one month ( I pay monthly) and that thereafter the subscription would canceled. However, when I got the cancellation quotation, I was quoted R1220.00, effectively putting me in exactly the same situation as last year. I did not get any notification of this and I never agreed to it being automatically renewed. I tried to solve this issue telephonically, but to no avail. This is totally unacceptable. There shouldn't be an automatic renewal clause that I did not agree to. Nico Kruger
