Mtn at it again...so fed up!!!

I am sick and tired of Mtn and their ****.. iv been trying to cancel my contract since March, April i get told i need to give a notice to Cancellations so that they can move my number to top up as i dont want an upgrade do you think Cancellations would ever pick up??? are there so many people cancelling contracts that they NEVER answer????? so i resorted to emails as if that helped, now today i must hear **** about my phone is still on contract and to top it all of with a cherry on the top i was told by the 30th of April my contract airtime and data would fall away as my contract expired the 14th April already i understood and had no problem with that but now the 1gig of data i bought and uploaded is sitting on my phone but nothing on my phone is working i keep getting told i have no data ***????? mtn is quick to block your phone if you miss a payment or take back their airtime and data when they say they going to yet they cant do their jobs and see to customers. it shouldnt be called \customer care"becoz as a customer i have not been attended to since March #highly****ed """
