Still waiting for feeback

As per the call centre agents I can only communicate to the social media department staff via hello peter as they are unable to give me their contact details and they cannot transfer my calls to that department. I need to speak to Cleo/ Joshua from that department as she confirm that my query will be sorted but nothing I am still sitting with a bill of R1900.90. The contract I signed with Telkom I pay R250.00 for each handset and R49 for 50 minutes and 500MB, should I need more. I call Telkom to give me extra minutes or data if there is a need, and for the past three months I have never requested extra minutes or data but I was billed as follows:<br> September R797.00<br> October: R904.00<br> November: R1 900.90<br> This is now the third month can someone sort this issue out.
