Shockingly poor service

Absolutely disgusting service. I am trying to cancel my two year contact after two years. I have spoken to the cancellations department 4 times. Been promised a supervisor would call me back twice - they haven’t. Customer services are useless. I signed up on November 2018. The myvodacom app says my contract ends on 40 November. The call center tell me that the information on the app is “often wrong”. I paid in December 2018. My contact therefore ends on 30 November and NO ONE will assist me with action it this request. Trying to hold me to an additional month simply because their system says the contact started on 1 December. I was so angry after all the wasted time - I told the man on the phone to count it with me: December is month 1 January is month 2 etc etc. therefore November is month 24. Time for my contact to end. Just a bunch of sharks and *****. Pathetic - and I am telling EVERYONE about it.
