Appalling Customer Service As Per Usual

I have just gotten off a call with 1 of their agents regarding my bill which I last paid on the 26th of February and today I received an sms stating I need to make payment my account is overdue. The gentleman who assisted me refused to listen to what I was saying and when I requested to speak to a TL he gave me the run around until he said I should hold the line... He must have forgotten to put me on hold or mute cause he started explaining my query to people besides him and them laughing. The 1 lady said he should just drop the line while others gave more appalling advice and they started making vile remarks about me and my query... I ended up dropping the line on my end after waiting more than 10 minutes for the agent to get back to me. This is not the first or second time having issues with rain. I am really disappointed especially to be insulted while I listened.

I have received the following on email as the reference of the call #***8 - Snowflake - voice ***
