Cell C useless

What a **** experience with these idiots, they quick to sign you up with your id and take your debit order every month. However when you cancel a contract and they owe you money, they never just refund it back into the account where they take your debit order. You have to phone this useless bunch and then have to answer up to 10 questions to verify you, then escalate to get a refund. Useless to the core
