I don't accept your contract fee increase

I have tried emailing, and you require me to send ID number and bank details via email for verification. I won't send this via unsecured email.<br> <br> Your online chat keeps disconnecting because it's too busy.<br> <br> An honest call centre agent suggested HelloPeter, so here I am.<br> <br> Sorry, I don't accept the contract price increase. I signed on at a contract price, I expect it to remain the same for the duration of the contract.<br> <br> I'll be sure to modify any contracts I sign with Vodacom in future. If you want me to sign any at all, sort this out.<br> <br> Keith Norris
