MTN MOVED MYCONTRACT PACKAGE WITHOUT MY CONSENT AND NOW I HAVE TO PAY FOR IT

IN THE YEAR 2022 I TOOK A PAC***E OF A LAPTOP AND ROUTER FROM MTN AT SPECIAL OR PROMOTIONAL PRICE. I SIGNED A 3 YEAR CONTRACT AND HAVE BEEN PAYING MY ACCOUNT UNTILL END OF DEECEMBER 2024. AT THE END OF JANUARY I RECEIVED A LARGER BILL THAN MY NORMAL MONTHLY PAYMENT AND ON INQUIRING WITH WHAT THE BILL WAS FOR I WAS TOLD THAT MY PACKAGE HAVE BEEN MIGRATED TO A NEW PACKAGE AND I HAVE TO PAY PRO RATA CHARGES AND WAS AUTOMATICALLY DONE BECAUSE I DID NOT RESPOND TO MY EMAIL AND SMS SENT TO ME. THIS WAS DONE WITHOUT MY CONSENT BUT IAM LIABLE FOR PAYMENT BEAUSE I HAVE 3 YEAR CONTRACT WITH MTN. I AM NOT SURE HOW THINGS WORK AT MTN BUT AS FAR AS MY LIITTLE UNDERSTAND IS CONSENT A CONTRACT IS SEALED AS SOON AS I SIGN IT AND NO ONE HAS A RIGHT TO ALTER THE CONDITIONS THER AFTER BUT OBVIOUSLY THIS IS NOT THE CASE IN THIS MATTER. I AM CURRENTLY STUCK WITH THE BILL I AM THREATENED TO PAY OTHERWISE MTN WILL COSTITUTE LEGAL ACTIONS AGAINST ME BUT AT THE SAME TIME I DID CONSENT TO THE PACKAGE MOVEMENT. THIS IS MY LAST OPTION FOR ASSISTANCE AS I HAVE TRIED ALL THEIR AVANUES AVAILABLE INCLUDING EMAIL MTN;S CUSTOMER COMPLAINTS BUT I RECEIVED NO FEEDBACK AS YET. MTN CUSTOMER
