Ceo won't assist when asked to

I have had issues for months now. i have escalated the issue to Gary Hagel office. now i get correspondence a day after i do. this is urgent. my calls are not being received! i am self employed. this is costing me my business!!i have to to speak to Shamble, his pa is rude. he does not respond. i have spoken to 12 consultants in one day! this is beyond a joke. i have mailed today reserving my legal rights and placing a deadline on this matter. you have 3 working days if not resolved cancel my contract and i take my business elsewhere. i am currently emailing 7 people including managers and they do nothing!!! Shamble you need to get this sorted or as you are currently treating me poorly you don't want me as a client. i thank you for the service till november.
