ZERO communication from Debbie Coetzer at Vodacom

Relates to K*** . I recently upgraded to a 100 Mbps 2 Terabyte Lte internet contract with a bundled S90 Router. This worked well, until it got slower and slower . Followed Vodacom store and call centre instructions. Speed was measured to be MAX 30. The Nelspruit Vodacom store technician laughed at me, and told me to send the product (router and sim card) back to vodacom . Since it was a pickup, Centrevo dispatched and it was collected by RAM couriers. I heard nothing since, Then I saw my contract was cancelled, followed up and was asked what I would like to do : in terms of contract advised them . Still No communication. THEN, I get the bill - I being billed for a 50 MBPS line for DOUBLE the price - and I dont posess the roter or sim - STILL NO COMMUNCIATION from VODACOM. I wrote an email a short while ago to Nicolette Jacks (who service was excellent) and Debbie Coetzer (who last emailed me - and has not communicated again with me ) . Since I did not choose to pay double for an inferior product , I will reverse the debit order until someone resolves this issue.
