Vodacom Canceled contract

Good day What the hell Vodacom I have a debit lodged for the 25th of each month, I changed banks contacted you to update my new details only to discover 3 days later you blocked my number... your walk in centres in vangate mall are ****ing useless as I went to 2 and all they tell me is I need to pay the reconnecting fee of R100 even though I explained to them the situation.. I get a response there’s nothing we can do u just need to pay it well I cage fed my bank details I was told they will deduct my 250 instalment.. I was then told I need to call Vodacom I explained my numbers blocked they then tell me .. I quote..sorry we can’t help u at the end of the day you will just have to pay it..*** I am not paying the reconnecting fee this needs to be resolved or I promise I won’t pay this contract and I don’t care if u blacklist me coz this is unacceptable
