STAY FAR AWAY FROM RAIN INTERNET SERVICE PROVIDER!!!!!!

if i could rate this company in negative stars, I would!! I have been an avid user of the 5G rain package since July last year. I then moved to an area on the 1st if May and plugged in my router, only to learn that I am NOT covered in a "5G" area any longer. I was HASSLING for two days straight trying to get someone to assist me and eventually when a consultant did call me back, told me that i need to downgrade my package to the 4G package, which I did. What i cannot understand is WHY HAVE I BEEN BILLED 3X FOR THE 5G AND THE 4G PACKAGE????? i purchased the 4G sim card on the 5th of May for R479. which this, on the app, states it is an UPFRONT purchase. I then requested my sim card of this 4G card be cancelled immediately on month end, as i have thankfully gone the fiber route. i cancelled the 4G card 2 weeks AFTER I MADE THE PURCHASE????? so what the hell am i being billed for? TWO debits went off, 1st one on the 25th of May for an amount of R220-00, and now an amount of R386.29 this morning???? WAT THE **** IS GOING ON????????? THIS IS ****************!!!!!!!
