Worse customer service

It’s now 6 months since I logged my query with Vodacom cell phone insurance. I logged my dispute on the 20th July 2022. I discovered that they double charged me for my cell phone insurance for past 3 months. I contacted Vodacom cellphone insurance and they mentioned that they will credit the account. This has not happened and to be honest I’m really disgusted about their customer service. The last conversation that I had was with Ben and he promised me that this will be resolved. Vodacom insurance a very quick to take your money but it takes a long time for them to credit your account.
