Unfair treatment

My land line has not been working from March 2015 .Prior to that it was not working and was fixed in February 2015 and it worked for only two weeks. I tried to contact the call center to report the fault but in-vain due to the ridiculously long waiting times. I eventually went to their offices at Keywest shopping mall and was told that my prepaid land line has been cut off this was done without any notice or warning and it will never be reinstated again. The fact is that I couldn't recharge my account because I had no line. I feel unfairly treated especially because my family have been loyal customers since the seventies.
