Please improve vodacom network in my area

Can somebody from vodacom help me have strong connectivity in my area please. I work from home my employer have a contract only with vodacom but network is terrible and I don't get it how come cause we are in a small rural Iqadi area near Osindisweni hospital just about 10 km form King Ushaka national airport. I even tried connecting my router near the nearest tower but it didn't get connection. network just comes and do and cant even open a web page. Its soo unstable and so inconveniencing. When I 1st move to this area I was using vodacom but changed due to the same problem but now I have no choice, even if they just install fibre network for me as Iam aware that they do have agreements with a number of fibre installers. I will really appreciate. Right now my working from home experience is a nightmare I have to pay for something that being paid for already and opt for mtn which also doesn't have excellent network. please help me I will really appreciate your assistance on this regard.
