Mobile number porting failure

Hi, In December 2023 I took out a new contract and ported my mobile number from Vodacom to Telkom. The porting took a few days but was problematic. Since my number has been ported I cannot receive calls from any other network besides Telkom. I logged a case with Telkom (***6), but to date there has been no resolution. Numerous calls to and from Telkom were in vain, as they always said that they were working on it or that it was escalated to Vodacom as it was a routing issue. It has been 6 months and still the problem is not resolved. This is terrible service and customer feedback from Telkom.
