Horrible service

I have been a customer with Autopage since April 1999 (15 years). It means nothing to Autopage & my support as a valued customer is not so valuable after all. At the end of last year a mail was sent to customers informing them that allowance would be made for customers coming close to their upgrade date to get an early renewal & secure an iPhone 6. The mail was sent in error, but instead of honouring it, they chose to retract it (not by mail to all, just me). They could have preserved my loyalty for at least another 2 years. I have decided to take my business elsewhere & requested to convert to prepaid in advance, confirmed it would be on 14/08. The consultant said it would be overnight. I had already entered into another contract in anticipation intending to port my number. It did not happen. I was told retentions do not work on weekends & would take place 1st thing on Monday. I have called every day now & told by the next day I will be on pre-paid. I still am not! In the meantime my monthly call & data allocation is loaded (I refuse to pay). How difficult is it to convert to prepaid? This justifies my cause to no longer subscribe to them & never endorse the company to anyone
