Telkom failing to issue a simple sim card

I took out an ADSL contract in Oct 2017 for a 4mbps uncapped home package which was advertised to include an integrated sim card of 1GIG data. this sim card is not included in the modem package and i was advised that i have to go in-store to retrieve it. So in February 2018 i went to the Musgrave Telkom sales store and requested the integrated sim card. I was helped by Ryan Grimett who issued me with a sim card and claimed that all was in order. In the days following, I attempted to use this integrated sim and found that it was not working. I then went back to the store in which i was told that the sim card had not been loaded onto Telkoms' working system and that it had only been linked to my account. so I requested a cancellation of that card and a new one be issued. I was told that this was not possible and I will be contacted by the integrated sim department who will resolve the issue. 4 to 5 months passed with no contact from Telkom. I once again went into the store in July 2018 and requested a solution. I was helped by Simo who explained that the application done by Ryan was not complete. He also assisted by writing an email on my behalf to his superiors to speed up the process explaining that its been months since my original query and I am still without the integrated sim card. That was a month ago, I followed up with another email a week later, everyone cc'd in the mail have returned read receipts to my mail but i have not received a any feedback from Telkom. Surely it cannot take 7 months for a simple sim card to be issued. Yet every month i am issued an invoice to pay for my adsl home package inclusive of this integrated sim. Clearly i am holding up my end of the contract but Telkom is failing to do so. I believe they should refund me for the entire package since October 2017 as they have failed to meet their own list of commitments on the package.
