Telkom LTE - complete lack of technical support

I reported that my newly installed LTE Router was running slow, and needed the aerial re-positioned/checked, This was on 31st JULY (!!!) using the 081180 call centre and I received a reference number for the complaint (***3). ZERO contact form anyone despite around 12 calls to the call centre. Discussed with 2 team leaders on the 081180 number (Zanele on 30th Sept and Elton Mfolo on 6 Oct) - no response from either. Eventually found Elton's email address, emailed him the 15th Oct and got a response 19th stating that an incident has been logged and I will be contacted shortly (ref 374872). It is now the 9th Nov I have had ZERO contact again from anyone at Telkom and have sent 2 unanswered emails to Elton.....the team leader!! I am paying for this lousy LTE service - they guaranteed I had coverage when I purchased it on their promotion. They installed the external aerial which worked for 2 weeks and then started getting slower and slower. Is there anyone at Telkom that has any respect whatsoever for their paying customers??? Eitehr they should come and sort it out or cancel my contract and take it back - PATHETIC SERVICE!!!
