They took payment and I'm not connected

Good Day

I paid for my rain to be connected and yet it keeps on loosing network and I called this morning I didn't get any help from the person who answered my call , AND THE WORSE WAS WHEN HE DROPPED THE CALL WHILE I WAS STILL TALKING, YOUR SERVICE IS VERY POOR

IM NOT ABLE TO ANSWER CALLS CAUSE THERE IS NO NETWORK AND THE DEVICE IS BY THE WINDOW

I DON'T UNDERSTAND WHAT IS HAPPENING BUT IM NOT HAPPY

I HAVE A ZOOM MEETING AND IM UNABLE TO CONNECT AND YET I PAID NOW I MUST BUY DATA TO BE ABLE TO DO MY ZOOM MEETING AND EVEN THIS EMAIL I'M SENDING TO YOU IM USING MY DATA...

IM NOT HAPPY WITH THE SERVICE AND YET ONCE I MISS PAYMENT YOU ARE CALLING ME ALL THE TIME
