BILLED IN CORRECTLY AND NOW FIGHING TO GET A REFUND

i am so frustrated and disgusted by the service received from Rain. i called their contact centre on the 8May 2025 to request for a cancellation as i was not happy with the service. i was advised that the request is processed and last day will be the 25th. to my suprise on the 25th i got debited R825.00 and ther router was already cancelled. called them to ask why i was debited because i paid in advance and was not supposed to be debited .....i was advised the termination was only processed the 24th and couldnt stop the debit order. now i am battling to get my refund. im told i should wait for billing department to calling me but do they know the financail impact they have caused me due to the imcompetent processes. i called and the agents are either rude or hangup on me. THIS COMPNAY IS A ****MER AND I WANT A CALL BACK TO GET THIS SORTED! I HAVENT EVEN RECIEVE A CONFORMATION OF TERMINATION YET IM BEING CALLED TO BE THAT THE COURIER GUY WILL COME COLLECT THE ROUTER BUT HOW IF THEY HAVENT REFUND NOR PROCESS ANYTHING ON MY PROFILE.................****EN IDOTS KEEPS PUTTING ME ON HOLD AND EVENTUALLY HANG UP ON ME!
