Terrible service from Rain internet service provider

Worst network ever... I migrated from 4G to 5G last month... Had endless problem connecting... Spoken to about 20 support agents already.. They gave me a reference number about 3 weeks ago by a support agent named Mbali.. 3 weeks later still no technician present to evaluate the poor internt connection... Today (28/04/22),i went through to the support centre and could hear a word the agent was saying because the agents in the background were screaming and talking to each other... She put me on mute and tried to talk to me again but still the agents didnt seem to care... She told me she will call me back n here i am again,, almost a hour gone and still waiting for her to return my call.... What miserable n pathetic service i have received, i had no issue with 4G network in my area however now with 5G,, its a nightmare... Im frustrated knowing that ill be paying for coverage that doesnt even provide me with an ounce of proper service... A proper audit is required within Rain as i feel that the customer service is the worst ive ever experienced thus far, very unprofessional n ********** customer interaction between myself n the agents...
