VERY unhappy client

After numerous calls, emails, queries and requests (since Dec 2014), I STILL haven't received any invoices from your company, yet you have disconnected me from the network.. I have been a client for almost 3 months and have hated every second of it. The service is pathetic and no one gets back to me on my queries, even after sitting with 2 of your consultants, on seperate occations, when they visited our company. I received threatening calls telling me my connection will be suspended, YET NO one can tell me what the amount due is and PS. I am on debit order... So stop treating me like a bad debtor!!! I would love to pay, so sort out your admin and provide me with invoices!!! Cannot wait for my contract to expire so that I can switch suppliers. I use my phone for work, so need it switched back on asap, or I am taking this further. I have mails and call records to prove that I have been trying to get invoices from you since Dec '14 in order for me to pay my account! Why am I paying the price for your terrible admin!! I cannot be contacted on my cell as this has now been switched off! So please mail me! Not impressed at all!!!
