Extremely bad service for my Huawei GT watch

I am highly upset with te service I received from Vodacom Key West. I upgraded at about 15 March to a new Huawei device and a Huawai GT watch as an exstra device. I waited a ou a week for my devices because I wanted a certain strap. When I received my devices the strap was to small for my arm and I asked for assistance. The assistant manager Brian assisted me and I told him what the problem was. He referred the problem to the Hauwai consultant. The service I received was unacceptable. He said I must only tighten the one side of the strap, when I showed him it is not possible he told me I must go to a jeweler and they must assist me. I think it is highly unacceptable to recommend such a propasal and I asked him if he knows how much I am paying every month. He went to the back and Brian told me he will come back to me with a answer. I never received any feedback and then I phoned the vodacom complaints line. They referred the situation to the manager Tshepo and he said he will solve the problem. He phoned me back and told me they ordered another link and wil let me know when they will receive it. The the lockdown happend and I understand that nothing could happen. Last week I contacted Tshepo and the Huawei consultant phoned and told me they are waiting for the part. Today I phoned Tshepo again and he told me he will phone me back. No reply. This is unacceptable service from Vodacom. I have been a customer for more than a decade and never received bad service this way. I am looking to shift my contracts the first chance I get to another service provider if this problem can't pe solved within the next 4 days!
