Bad service

I cancelled a contract in March as it was not what the consultant sold me then they debited my account for almost 3 months after a huge fight the debit orders stop just to get an email yesterday they handed me over to lawyer for non payment. I am extremely unhappy because I'm buying a house n this is reflecting that I'm a poor payer ... I told the consultant last time I've never been so upset wit a company.

If you guys do not fix this I'm taking further steps

This is ridiculously
