Poor service delivery Vodacom

Wost experience ever. Vodacom is unable to connect data package on my kids apple/ iwatch. Have been paying for months and following up weekly with call centre. Keep promissing that the technical team is fixing the problem. Say they don't have a physical place where I can take the devices in for them to test and fix. Vodacom branches just pull up shoulders and refer me to Technical support. Every time they request me to re-load and re-set devices promising it will be fixed in 24 hours. Just so frustrated as they keep promising to fix e-sim/data plan on their side.
