Rain Mobile network provider company

Today I called Rain and spoke to Asinah from the Gauteng branch requesting to speak with a team leader and she told me to call the Cape Town branch for assistance with my query. I then called the again and spoke with an agent named Aviwe from the Cape Town branch regarding my ****** Rain 4G SIM card and requested to speak to a team leader or manager. She told me that there are no team leaders available. I've been told that Rain will load my new data when I get my new SIM card since they were not able to block my ****** sim card and today Aviwe told me that I won't get the data that is due to me even though I reported that my Sim card was ******. I never used my 2G data that is due to me this month hence I've been calling the call centre to speak with Melissa the team leader who assured me that she will assist me with getting my data for the month of August. I feel like a fool, running around like a headless chicken. There's not even an email address for complaints or escalations on the Rain app or website. I'm so furious and unhappy with the service from Rain.
