Very unhappy client

Hi i would like to lay a vomplaimed.and need an explanation.we were clients of vodacom for many years.my husband opened 2 contracts with them.eventualy the account was in arears because vodacom didnt add my contract number on hes account with hes contract number.so the acvount was in arears with 6900.last week q5e had made a payment of 7000 and wanted to cancel both contracts.so today 14/02/2022 my husband phoned them and they sayd hes number is canceld but to cancel my contract we must pay an additional fee of 1700 that would be the cancellation fee.so in other wordd i have to pay more than 8000 just to cancel my contract with vodacom.i am not happy.
