Very bad service

Hi. We loaded a hello peter complaint for very bad service from vodacom and still no wifi installation. We were contacted by Ashley on the previous hello Peter complaint, who said he will ensure the matter is resolved and installation done but to date their has been no further communication from vodacom and on a follow up this morning, I was told there is no ticket loaded for installation. Not fair of vodacom to accept a sale if they are not able to complete the service as there are several other options. Its been 3 week's since sale of contract for home fibre and no installation done.
