Vodacom Network coverage

Vodacom has the worst network coverage the past couple of months,Every one i talk to from friends and family over northwest,Gauteng,Kzn,ect.All have the same problem,Clients struggling to get through to me because of Vodacom,they always have (No Service).If I didn’t have this vodacom contract i would have go over to MTN ,but as soon as my contract is over ,im switching over to MTN. This is very bad and unprofessional of vodacom,we pay for our services and this is what we get(No signals) everyday,then why must we pay then!Or if cell c still does the contract switch,i’ll rather move to them instead of waiting for my vodacom contract to end.
