Incompetence at the highest level

Absolutely perthetic. Signed up with Vox as on 1 July. I get billed from June. Informed them countless times to reverse the billing as it starts only in July. A month later nothing g done. I emailed them countless times informing them that no payment will be made until they sort out my account. Today I received a letter saying they going to suspend my account if payment not made. They clearly do not speak to eachother with regards to account queries
