Appalling service Vodacom

I opened a new account in order to take over my deceased husbands account as I am now running the business. On the 12 01.2018 I paid my account R3012. Unkown to me as my husband's account was closed Long Beach mall paid the closed account. I have been in contact with Vodacom so many times I simply can't count how many and emailed them. Long Beach Vodashop did as well. To date after acknowledging the problem nothing has happened. And when I see the emails or speak to anyone they are never the person it appears that wants to take responsibility. Therefore I am going to Telkom as there service level is 100 percent+&
