Non existent Customer service fnb connect-sim

<p> I took out a data contract with FNB, sim card was delivered and it gives a number to dial.to activate the sim card, I have had it for 2 weeks now and still the card is not activated, can receive calls but try call out and it says the sim is not active. After numerous calls I get told the same story, we sorry about this and we will escalate your query. I have now had enough, want to cancel the sim but did buy airtime and now get told they cannot refund me the airtime. Their service is disgusting and I wish I never took the sim card. What is happening to the service at FNB? Have they just got too big and don't care about customer service anymore!!!!!</p>
