Alienated, disgusted customer service

I am at a loss of word, i have been begging for a manager to return my call as i want to resolve my account query. To date no manager has call me bacj as the staff keep on advising the query will attended to and i have been logging queries, sending emails but nothing. I have been treated in this manner when you as the customer are requesting assistance. I have made it clear i want to communicate but i sense they have *****ed up their admin and are not sure what to advise me. I have my proof and they contact me with their books and we try to resolve my account query but they have shown they do want to communicate with me and not a staff member but a manager that can obtain my account data and we resolve my query. I want to make payment but they to see where they made an error. I would not recommend Supersonic to anyone, i should have followed my instinct when i encountered my first issue in August when app**** to have their services and they coild allocate my payment.
