Rain disgusting service

I purchased the mifi router and unlimited sim in May. On the 4/06/2019 the router got lost as it fell out of my husband's pocket when he was sitting. I contacted Rain on the 05/06/2019 to ask them to block the sim in the event of someone finding the router and using it. I was told by Itumeleng that my request would be actioned in 24 to 48 hours. 2 days later the sim is still active and someone has logged on and has been using data. I processed a cancellation on line which was only effective on 30/06/2019. I called again spoke to Palesa and Thabiso who then advised me that they do not have the ability to block the sim but I rather need to do a sim swop to resolve my query which they then requested on my behalf and requested me to retract my cancellation. It is now 2 weeks later still no sim delivered. I called again on Tuesday after sending 2 emails with no favorable response only to be told their back office approved the sim swop but they've been too busy to issue it for delivery. Eventually the sim was delivered yesterday only to discover that it cannot be activated as they sent me a sim card with no serial number and it cannot be traced by them. So now I'm sitting with no WiFi for almost a month, *********** feedback from the agents at Rain and a defect sim card that I can't use but am still being reminded by Rain that I must pay the subscription fee for this month even though I have not used any data. After market customer service sucks and agents are rude with no sense of urgency. They are not s****ed properly to even handle the queries received as they give you conflicting information and when there is never a manager available when you request for one. Now I am out of pocket for airtime and data that I had to purchase due to the inefficiency of this company. Still no follow up done by them, query still not resolved.
