Bad customer service MTN Boulders Midrand

I lost my contract SIM card in Jan or Feb I went to Mtn Boulders in Midrand to do a sim swap the agents had no sense of urgency they were on their personal phones after what seemed like 2 hours I was attended to I was told they are offline ok the following month I went again during lunch time same thing happened and I was forced to leave because no one attended to me for 45 minute’s In April I went to Mtn at Festival mall I was told they do not have SIM cards at least their service was proper . Last week on the 10th of May I went to Boulders again I was not attended to they were busy chit chatting until my lunch time was finished so I’m paying R599.00 for a sim I don’t have my question is will I get the minutes and data once MTN decides to assist me i feel very failed as a Customer
