Mweb/Ping'd Sales Complaint

To whom it may concern<br> <br> Yesterday I received a call from an individual purporting to be an agent from Mweb (turned out to be from Ping'd) asking if I would like to move my internet data access from Telkom to MWeb for a cheaper price and increase from 2G to 4G. I agreed and signed up. I then received a message from something called SafetyBox informing me that my account had been activated, which had not been mentioned to me in the call. I telephoned Ping'd this morning to discover that this is a 'Value added service' costing me an extra R50 per month. I immediately cancelled this service and any other extra services. I am now trying to cancel the account entirely as they have acted in bad faith. Apparently they are offline - they are unable to cancel my account, but able to cancel Value added. Please can my account be immediately cancelled. I will be returning to Telkom for my data.
