Billed in error. Nobody helps to get this correcte

During November my internet and voice service was suspended, due to my credit limit (which I know nothing about) being reached. This happened because Neotel billed me for services which were not supposed to be billed for. After receiving my bill I disputed this under the following reference number that was sent to me. SREQ_***. It has been 6 days since this reference number was generated without any response, so I called their call centre - my only option. The consultant claims she could not get hold of the finance department and was unable to give me any satisfactory answers.<br> What is wrong with Neotel? Very unsatisfactory indeed. The previous complaint I made - associated to this issue, was rep**** to on Hellopeter and nothing further!<br> What a joke.
