Despite requests contract not cancelled

After numerous complaints about connectivity issues, Sonny from technical dept contacted me and investigated. He found that there was no connectivity in my area and stated that the only long term solution was vodacom installoing an additional tower. He then advised me to cancel the contract through escalations for which i sent an email on 5th November 2022. He also undertook to follow this request through and stated that vodacom will not penalise me of charge me for lack of service due to there being no coverage, HOWEVER, VODACOM STILL CONTINUE TO PRESENT INCREASED DEBIT ORDERS EVERY MONTH! WHY HAVE YOU NOT CANCELLED THIS CONTRACT? Your service is pathetic!!!!
