So I have 3 adwords accounts that I opened under 3 different email addresses so I could take advantage of the 100 when you spend $25 codes 3 times. I didn't quite understand how it worked, so I just spent about $100 or so on each account thinking I'd just not get charged, but I don't think that's how it works anymore. it has not been a month yet on the accounts, about 3 weeks. My question is, can I just change the credit card address/expiry date under adwords billing so that the upcoming charges won't process and go through and I will basically abandon the account? Will google get a collection agency after me for doing so over $25-$100? The 3 accounts used 2 different credit cards that were my REAL cards though. One of them was cancelled earlier and google tried to pull money or do a check and as a result one of my accounts lost its promo code and now has a bill of $90! I called to get the promo code reinstated and the google CSR said that the promo code can only apply to future payments, wtf! I don't want to pay that, it's ridiculous. So I plan on not paying that if possible. Should I just pay the other $25 accounts too though? I don't care of my website or my name is banned, I don't care to use google adwords anymore. Any advice on how I can not pay these would be appreciated. I should note that I do NOT CARE if my website is banned from adwords, I'd rather pay nothing, but I don't want to deal with collection agencies. I am in Toronto, Canada too.
