Billing & cancelation

Canceled the contract in March and was lgiv3n that the last connection day would be 30/04/2026.Then on 23/04,they decided to disconnect my line which I spoke with them to reconnect the next dayy but without doing aydue diligence, they reconnected and billed me for that service of which it was their own error.On 26/04,I realized that the account debit order amount was wrong,notified them which they logged a call for it to be enquired.During that conversation they did say it was an error on their side.Since then,I have been in communication with them about that then on Tuesday,12/05/2026 they wanted my account details which I supp**** then asked when it will be reflecting in my account and was told that it's gonna take 2-3 days the today when I enquired I'm told of 5-7 working days.At this point,I'm feed up and want to reverse the debit order.
