SUPERsonic... Nothing super there!!!

How many days does the month of March have??? So it takes you 20+ days to acknowledge cancelation of my line, yet at exactly 00:00 on 29/03, you suspend my service... That was paid for the WHOLE of March... AND as per your one liner email, 'the month of March' is the notice period... Last time I checked, March has 31 days... Not 29... I have spent HOURS on the phone to your call centre, sent over 15 mails, lodged a complaint on every possible platform, and then just for kicks you'll irritate me one last time and ensure I'm offline AGAIN... I hope anybody wanting to do business with you rethink it over and over... And use ANYONE else but you... You have ****** my money, you have ****** my time... Thank goodness I will NEVER deal with you again!!!
