Vodacom Poor Customer Service and Contract Dispute

My contract with Vodacom was suspended in Feb 2019, however they have still billing me for airtime that I am not using. They now handed me over to attorneys for an amount of R8000 which I do not understand what for because my installment was R350. They have not even contacted me to say that failure to settle the account will result in my account being handed over.

I called Vodacom to request a copy of my contract as well as my invoices to compare to amounts and see how it comes up to R8000. I was put through to 5 different people and they all say the do not have a copy of the contract (how pathetic is that). I also spoke to a lady who said she will send me copies of my invoices but I am still waiting. She then asks me questions of which bank I am with, what is my account number, how does that affect me getting a copy of my contract.

Failing to send me a copy of my contract will then result in me disputing the amount owed to them hence this will lead to me contacting my lawyers.
