Our main complaint is over ( a ) how XXXX company handled a case for which we owed NO DEBT ; and ( b ) how Diversified Consultants Inc is constantly harassing us to pay a debt that we do not owe. 
We signed up for a phone contract, paid a deposit and within a few days we cancelled the contract over the telephone and the CSR advised me to not accept the phone upon delivery. The deposit was refunded to us as the CSR advised. Shortly after this, we received a bill of {$190.00} from XXXX. We called another CSR explained that it was a mistake and that we should disregard the bill. A month later, another inflated bill arrived and we called XXXX again. We were told the same story again by another CSR. We continued to receive at least another inflated bill. In late XXXX we called XXXX for the fifth time and yet another CSR and a project supervisor confirmed that the bill was sent in error and that we did not owe any monies. We received a confirmation email telling us that the handset was returned and that " a credit card refund for the returned device '' would take effect, and also that " the XXXX on the account '' had ended.Handset Order Reference : XXXX. Two weeks later we received a letter from a debt collector DCI informing us that we owed {$190.00}. Given that we have NEVER used this phone, nor accepted it, and that we cancelled the contract as advised by a XXXX CSR, we are being harassed for debt that we never ever owed. We have contacted both XXXX and DCI and were advised that our case was closed with XXXX XXXX and handed over to a debt collector. The fact that this even occurred after our numerous attempts to reach both XXXX and DCI is absolutely appalling. We are complaining against both XXXX and DCI for their false debt collection, poor handling of our case, and constant harassment and stress for something that we should never have had to face. We also have evidence of the credit refund from XXXX indicating that the contract was cancelled in time and never used. And we have an email confirmation from XXXX confirming that the handset has been returned. How is this even possible?
