Annoyed by Mondo

The experience I had with this company is baaad. I remember last time a had a good review of Mondo after they gave me a good over the phone service. After the call, they never followed up with their promises. After many attempts of having my case resolved with them I ended up counseling my contract with them. Even so it was confirmed to me that the contract is suspended and void. Just a few days ago I received a notification from my bank to state that I had insufficient funds for their transaction after being promised that my contract has been cancelled. Nothing good came out off our relationship. I was unhappy the whole time and kept having to call over and over to have one thing or another fixed. And still after the cancellation they still trying to Bill me.
