Nothing to do with Telkom

I received a call yesterday 18 August from a lady who said that my Telkom ADSL line would be discontinued shortly and I would be receiving a new Wireless router for the internet. So I would carry on paying Telkom for my landline for phone calls, and I would receive an account of R399 per month from 15th of next month, for this new router with all its bells and whistles. I smelt a rat when she asked for my bank details and stupidly I gave them to her, when she said that she couldn't do anything with them without my signature. Documents would be emailed to me so I could read terms and conditions before committing. Well I received an email thanking me for ordering the new router. This I did not do and could not read the terms and conditions as the link was invalid. I immediately emailed her back and phoned a Michelle to cancel as well. Not sure what has been done, but wanted others to be aware of this. I phoned Telkom who said this is a **** and NOTHING to do with Telkom. SO BEWARE
