Bad Service

Just spoke to the call center because they keep on sending me SMS's but the account does not belong to me. They then told me I have to phone a other number to ask and ask them to remove my number.They then told me to block the number .... I then said no I want to talk to a supervisor, the agent then told me they need to sort out the call, I told him I want to talk to a supervisor I when rep**** and told me they are busy. I then told him that he needs to go and collect them. I did explain my issue (this is the second time I called the call center) do not want to spend my money to clean up their issues. they drop the call.... very professional.
