Poor cellphone reception from Vodacom

I have logged calls for poor cellphone signal and dropped calls in my area but the response is always we plan to upgrade infrastructure somewhere in the future. I now sit with 4 Vodacom contracts this hardly usable. I had to get a pay as you go with another service provider just to make phone calls. The service was fine for years but have deteriorated over the last few years to the point of useless as far as calls are concerned. With our homes becoming our offices this make life without Telkom phones extremely difficult. In 2021 this level of poor coverage in a major city is really 3rd world and I would like to think Vodacom can do better.
