Vodacom connectivity really unreliable

Experiencing a lot of connectivity issues...super unreliable fiber wi-fi. Have to restart router multiple times per day and still waiting gor tech support despite having called in the problem 3 times in the ladt 2 weeks. Also experiencing dropped calls on a daily basis. Vodacom's connectivity is unreliable and frustrating. We've been Vodacom customers for 20+ years with various devices and contracts and we are seriously considering switching service probiders once our contracts terms are up. Any suggestions?
