Feedback on MTN reply to sim \no service"issue"""

Hi MTN. Thank you for your response. Since my posting on Hello Peter 2 weeks ago, I have emailed customer service, tried getting hold of call centre, even visited Northgate branch TWICE and Cresta branch once, and still not sorted out. Yes your system shows my data contract is active, but it does not mean its actually working. Tonge from Cresta managed to get the dual sim that is in the Wi-Fi ****le to work. But still not able to get the sim that I use in the ipad to work. Northgate branch did initial upgrade contract. Before the upgrade my dual sim was working perfectly for both wifi ****le & ipad. Why would an upgrade change anything? After northgate upgraded customer service advised me the upgrade didnt go through. 19th April i went to Northgate as I had \no service"since upgrade. They did a sim swap and said to wait 2 hrs for activation. On Sunday 20th i went back as new sim still not working. They said swim swop did not work. Said swim swops never work if done over weekend. Also said that dual sim has issues but before upgrade all was fine"
