Worse Service ever Billing incorrect

God day All

I have been up in arms since yesterday to try and sort this out issue and I need it to be sorted ASAP.

I took out a router month to month contract sometime in October and realized that the plan did not meet my needs at all I called MTN looking for a better plan and I was offered another router which I had to pay R699 Monthly.

The router was taken out with a company name CCS and the consultant told me I had to pay a Pro rata of R744,10 this includes the router plus internet for the month of August till my next bill on the 1st of September. ( see Below)

The router arrived number ( ***) I took the old router back to MTN Store as I was advised, and they advised they will cancel it on their side (***). From my calls and being sent from pillar to post I was told that my contract for number (***) was migrated ( upgraded or downgraded not sure ) Please advise where the communication was sent of this Migration as it took place on the 22 of August but I returned the router on the 24th of August. Why am I charged a migration that I did not approve or services that I did not use ???Instead of the plan being terminated it was re activated please show me how I approved that. I have called now and cancelled as it was never done with ref number IRMS***.

Now coming to the second router as above screenshot I paid the Pro rata already but on the below invoices I am charged another pro rata why ?? How many pro rata does one need to pay as I already paid the R744 as I was told by the consultant as the pro rate. The R607.83 charge what is it for as I also do not understand it. This was never communicated. I was told after the R744 payment I will pay the R699 every month. Why do I need to pay R1836,23.

Whoever is attending to this query must give me all the information if you do not know escalate this to management as I am angry and inconvenienced now.

Spoke to CCS they told me they did the signing me up and the invoice was generated by MTN and you need to rectify this ASAP.
