WHAT DOES IT TAKE TO HAVE YOUR PHONE UNLOCKED

On Tuesday 16 March I received an sms to state that my line was suspended - no prior correspondence or warning. Approximately 1 hour later I paid the outstanding balance and emailed proof of payment to [Email Removed] Approximately 3 hours later I contacted collections to confirm that payment had been received and to find out when my phone would be opened. I was told that they had received the payment and that the phone would be opened in 1-2 hours. It is now Thursday 12.20pm I have called collections at least 5 times to find out why my phone line is still not open when the payment is reflecting. STILL NO ANSWER I am put on hold endlessly only to have the call dropped. Quick to take your money, quicker to cut you off but unbelievably slow to reconnect your line.
