No response from Telkom for LTE line upgrade

ordered capped LTE via mobiletalk and want to upgrade to unlimited. Mobiletalk cant help, directed me to Telkom. Telkom customercare directed me to Telkom Shop (went to Eastgate shopping centre Telkom). They couldnt help, redirected me back to telkom. Have been sending messages via twitter from 18th December with a response from Telkom requesting my contact details which i have done same day. No response, resent on twitter again on 20th and 21st Dec 15, only response on both messages is that they would provide feedback. Its now 6th Jan 16, no feedback yet. All i want to do is upgrade!!! spend more money with Telkom and have had no response.
