No service from vodacom since January

This is not the first time I have a problem with Vodacom. My Dad lives on a farm and recieved a 2 GB booster that is now faulty! He logged a call around the 25th of Jan 2018 to get this sorted still NOTHING happened! We even went to Harrismith Vodacom shop, they would have phoned him back its been MORE than a week and still heard NOTHING from them or anyone!!! Your service is only going backwards but you claim to be the best service provider!!! Hes got no signal on the farm and need to run a business!!! This need to get sorted ASAP. He has been a client since vodacom started and that is how you treat your clients that is loyal to you from the beginning! I am disgusted!!!!
