Complaint Review: Hewlett Packard

I purchased a lifetime contract for computer problems about Dec 2013 for approximately $500.00.  The only problem is that the individual did not leave a phoe number where he/she could be reached if I needed a problem fixed on my computer.   They only called me once a month to fix the computer.  I tried to cancel the contract and they told me that I had to pay more money to cancel.   I indicated to them, that I would keep the contract but not to call me anymore.   EVerytime they called me, it was from a different telephone number.  I have received at least 14 calls from 14 different numbers.   If I tried to call any one of those numbers they were not  in service any longer.  The last call I receivd the individual asked me to give my credit number so he could refund $400.00 back on my credit card for the refund.  I gave it to him like a dummy.  A couple of days later, my credit card company  called me and indicated to me that my account was compromised in the amount of at least $1000.00. I was not charged for this amount.
