Very bad service

my daughter in law keeps getting calls in connection with my other vodacom accounts. She has requested that they call me after 5:30 in the evenings as I am unable to calls during the day as I work with students and the student finance office. I am not prepared to discuss my private account in front of students and cannot send them out my office to take a call. I have been trying to cancell two contacts for the pasdt 2 years and each time they keep extending the contract even though I asked for the account to be made prepaid as it was my late husbands contract and he passed away in 27 July 2021. If they need to contact me they will need to call after 5:30 in the evenings on my number as my daughter in law i not always at home. The data contact the date keeps expiring as I do not use it as I have unlimited at home and connect to the works wi-fi when at work. this service is really not acceptable. Can simeone please call me URGENTLY to sort out these issues. A consultant even called them from Carnival mall regarding the accounts that needed to be cancelled. they are still active. They are calling from *** and I have not had any missed calls from this number.
