MTN and First National Bank - nightmare personified

My previous data package was R339.00 a month. I received an email saying that my contract had expired and they were debiting my account as month to month for R1207.00! Plus any additional charges. I immediately phoned (no reply) emailed complaints department (reply but to say they would would reply - which they didn't, to cancel with immediate effect. I also stopped payment with First National Bank. I finally had to go into one of the MTN Offices to assist. They logged my cancel and said they would contact me. On the 30th June R1207.00 was removed from my account by MTN! After a very long wait for customer services at First National, the reverse of funds and at a R45.00 cost was done. Both MTN and First National were breaching their contract but I was the one who had to pay!!!
