I am now speechless

Very bad service and this is my second time writing on hello peter. It has not even been 3 months but it's been such a headache! How am I supposed to rely on their security services with such bad service? Anywho, I received an invoice and queried about the correct amount as the technicians had advised that I had lightning cover insurance so I would pay a lesser amount but the invoice I received did not reflect as such. I have been querying for over a week just for a correct amount in order for me to pay and I am still waiting........
