Primus the Worst

I moved to Primus because of the recommendation from this site - Big Mistake i made.

I have been receiving calls many from abroad ( I am sure Primus gives the number out) it is ex directory and only Primus have my number. I rang Primus that I was upset by these and wished to change my number and did ask them if i would get charged and they said no because it was my first time.
The number got changed and the following month they took out £15.00 from my bank account because i pay by direct debit. I rang and made a complaint and was told that it was taken out by mistake and they would refund me. The following 3 months they still took out my monthly charge without refunding me. I then cancelled my dircet debit and they charged me for the bill and still didnt show my refund. I rang them up again and said i want to cancel my contract which had expired a month ago. They said that when i changed my telephone number a few months ago i agreed to going into another contract. I did no such thing. I was told that i owe for this months bill and the money was refunded to me already i made the 1 months payment and i then checked all my statements on the internet and did not see no refund. I then rang up again and when i asked when did i get a refund i was told that it is going in this month for June, i said why did i get a bill this month in June to show that i am in credit and dont owe, he just said it wouldnt show and that i am £3.49 in credit, i asked that why was i charged £8 when i rang up earlier and the lady said i was paid the credit a few months ago. They are just trying to get money out of me. Never trust them, check your bills regular.
I have now made a complaint on their website and have given them 7 days to reply. I hate this company they just want their money and dont care about their customers, the worst one i have been with and wouldnt even go with them if they were the cheapest.
