Pathetic service and policies

I took out a LTE data ONLY contract with vodacom in November 2019. There was no device involved in the contract. Due to extremely POOR speeds of aroud 9mbps consistently, i am struggling to complete my tasks due to SLOW speeds. I have contacted vodacom customer care several times to no avail. I have an mtn contract as well and consistently get speeds of 100mbps. Vodacom refuse to release me from this data only contract saying that i have signed for 24 months. I am no stuck with this pathetic service provider and ridiculously slow internet for another 20 months. All other service providers offer month to month contracts for data only, no device involved.

I WILL NEVER EVER SUPPORT VODACOM AGAIN.
