Bloood suckers!!! ****** Telkom! Poooor customer service!

I took a contract 2 years ago, it supossed to finish today on the 10th, on the 29th i came to set a notice that my contract is coming to an end on the 11th,the lady who was helping me told me that im only gonna for for the subscription abeing R90 on both devices, that was on the 29th,that was understandable and led me to taking a new contract, now when they aahave to bill my account that R180, initially my contract amounted to R499, now the invoice comes back us as R790. I went to the store to check with them, they could not give us a clear answer, instead they stopped service with immediate effect yet we still had credits on the sim card, we went on asked why is the sim card de-activated, they reinstated the simcard immediately again but now we had a zero balances, and they telling us that we are left behind, how so because they have been debiting my account! I want answers from telkom, the sim card numbers are *** and ***. I visited the mimosa outlet in Bloemfontein. Both the assistants were rude to us, it was the lady and the gentleman! This is my money, and business contact, now my clients cannot contact me yet i will be liable to pay again for something that doesnt make sense! I want answers!!! They gave me the order number ***A, and cancellation case number ***9 and number ***0! I want answers????!!!
