Sales consultant mislead clients

I was signed by a Mweb Consultant in April and she **** with the terms of payment for the contract. I had initially chose Vuma reach and paid for it and I was later advised by that consultant that Vuma is not available in my area and had to switch to Comtel. I had paid R448 by then, she advised that the balance for Comtel will be offset from the R448 that I paid and the remainder would be deducted from my account. Later in May I saw that I’m being billed for both Comtel and Vuma, I then called Mweb and they confirmed that my order for Vuma was cancelled and everything was in order.Come end of May the debit order goes through for Comtel but they reverse all the payments allocated from the R448 of the Vuma. They disconnect my WiFi. They don’t refund me my balance due from Vuma. When I call I’m being advised that I was supposed to have been refunded and now I owe for Comtel hence they disconnected.We now in June and they never communicated this previously. The WhatsApp consultants Yusri **** and said everything was I order. I’m not left with a debt and a refund which they can’t offset each other,whereas the sales consultant said it was possible. They chase sales and mislead clients!
