TELKOM - SERVICE NON-EXISTENT

When I originally took out a contract with Telkom, the gentleman assisting clearly was not listening and instead of moving my data to the current simcard he left it on the old one, since then it has been an uphill battle to try and get this sorted, my contract expires in December 2019 and I have absolutely no intention of taking any further services with Telkom. Have emailed them on their website on the 5 April and again on the 30 April and all you get is an acknowledgement of your own email. Clearly Telkom doesn't care about their customers, nor are they interested in resolving any issues speedily. I have now taken a new contract with another service provider due to their lack of after sales service however still need the data transferred as was originally asked. Honestly if they want to retain their customers provide the SERVICE. Can someone please have this resolved before December, hope I'm not asking for too much.....
