Vodacom payment

My debit order went off 26th May 2020, during lockdown, I obviously wasn't working hence no funds in my acc. Anyway I started working 1st June, and made Payment at a vodacom store on 9 June 2020. I called vodacom to enquire if they've received the funds and they said they haven't. I called about 20 times within a 3 week period and vodacom kept telling me the same thing, I owe them so and so.. The manager at the vodacom store emailed them proof of payment and so have I about 3 times. Vodacom keeps telling me to go into the store, they need to allocate my payment to my account, and the vodacom store says, when I make payment and provide them with my cell number, it automatically goes to my account. I have seriously had enough, I am not calling the store or vodacom again, this is absolute BULL****! Hopefully someone reads this complaint and contacts me to sort this out. I have had enough, I did my due.
