Vodacom fibre

After our relocation from JHB to Brackenfell we got an installation of vodacom fibre with a Nokia router, at first we had the Huawei router that was working perfectly fine. Ever since we got this one (Nokia) we can’t make WhatsApp calls or video calls, my husband cannot access his banking app or super sport on his phone or laptop. We logged a lot of complaints and were told that this issue will be resolved since last year September when we got here. We are thinking of changing this service provider but we are stuck because of contract we have with you. This is sick and unnecessary expense as we have to buy data to cater for the mentioned services while we have wifi at home
