I started notifying then of my wish to end my contract in Apri. They continued debitting from my account until I wrote to them again and they said last debit would be end of June. They did debit and even came to fetch their router. Now I'm getting sms texts that they will be debitting again end of July. For what? Rain pls accept that my contract with you is over and leave my bank account alone. Your cancellation process is the pits! Fix your mistake Mmaphuti Mmushi ***
