Services over charge [**********ly?]

1. From Nov 2014 thru Jan 2016 I was charged for a 10MB line whilst infrastructure only supports a 2MB line. Dispute logged but was rejected without contacting me. Eventually spoke to someone but on calling back for an update the call remains unanswered. Problem remains unresolved.<br> 2. Despite the ADSL being cancelled I have been billed for the last 2 months for the data portion. How is this possible when there is no ADSL line? <br> 3. Additional Anytime Extra service added without my consent to my account and billed for in Jan/Feb. Despite this being cancelled I was told I would have to pay for it and there would be no refund. I never asked for it?? <br> Please can this be resolved once and for all. Doesn't it seem like ***** to be charged for something i could never use and for a service I never consented to?<br>
