No Feedback for 2 Months - On line Fault

After sitting without internet for almost two months, I cannot believe the incompetence of MWEB. They first mess up an investigation which they knew they were in the wrong with, which we still have to pay for and then they completely miss logged a complaint which we receive no feedback for, but when we call them find out that our number has been given to someone else and we have been paying for their line for the last two months. No one picked up the change in details but suggested that they will send a credit for the time that the line was not used. In the meantime we have been using data to at least access the internet but no one will be paying for that except for us. So I am now sitting with a contract which I have to pay, else I will be put into bad credit.
