Cancelled a polka account 3 years ago

I am an very unhappy Mweb client- I bought a computer on HP through Polka and paid monthly R273 +/-. Polka gave me an email address - one I never used. When the lease was over - I presumed the polka email is also done because I never used it. Not once did I send any email from it or logged into it. Then February I cancelled a email address my Husband used and I also mentioned that the only email address that I should have is the one I am using now. I did send a email in 2012 requesting Polka to stop any email addresses or any other services - in February again I requested Mweb to see that all services is cancelled but my email address - then I still saw this R59-00 going through my bank - I got very cross and went to the bank and cancelled it - I send email to accounts department - now they suspend my email address I am using - Mweb your service suck - Your accounts department received email from me - still no service - You are going to lose a very loyal client - more than 10 years I used Mweb - but from here on you can believe me I will post on Facebook and Consumer will receive my complaint
