Vodacom Elite gives disgusting support

Vodacom Elite in Umhlanga sold me a Samsung Galaxy November 2021 with a contract. 3 months later the phone was blocked, Jobcard ***6 refers. When returned to me, the speaker was faulty. Being deaf, I needed it to work. Once again Shelley Centre returned it Jobcard ***0 refers. It's been over a month, first I was told via SMS the phone is lost, then when Shelley Center called, the phone was found and they did not have spares. I was told by Josh he needs a signature, spares are now on hand. Up to now, I have not been given a delivery date. I am desperate now to get this phone, I am paying for it, I do feel that Vodacom Elite has failed me. I would appreciate you assistance in resolving this matter.
