Worst service ever

They do not even deserve the one star that they got here. As other people on here complained about. I cancelled my Cell C contract in May 2020. I was informed that the last debit order date would be 30 June as I had to give 30 days notice. This I had no problem with. Then 31 July another debit order went off my account. When I phoned the support center, the lady there was very helpful. She went back to the recordings of when I phoned in to cancel the contract. The previous person I spoke to with regards to the cancellation, never cancelled my contract. She escalated it as she acknowledged that is was their fault and that they should be refunding me the money. Earlier this week when I phoned to find out what was happening as no one phone me as promised, I was told that the credit note was done and I should receive my refund by the end of the week. I just received another statement from Cell C with a debit note and a credit note on it and another invoice. *** - They did not do their work and now I am getting penalized for their incompetence. As I am typing this I am holding on to speak to someone at their helpdesk. This takes forever as well just trying to get hold of someone
