Awaiting resolution for 1 month - SHOCKING SERVICE

SInce 3 June I have a ref case pending for resolution for my phone. I cannot make calls and despite various calls and speaking to Michael and Thuli and emailing Nkateko Ngobeni who I am told is a manager and would resolve the issue - I have had ZERO RESPONSE and ZERO resolution!! It is almost a month on and this is affecting my business and my elderly Mother who cannot make calls. This is RIDICULOUS!!! I am not sure where else to turn since phoning, emailing and whatsapping is USELESS
