Unhappy service

I've had vodacom Fibre for 2 years if not 3 years. I've had and still have a month to month with Vodacom wifi . I must say your service is bladdy pathetic. I've been trying to lower my speed because I don't need a high and very fast speed . I went into the vodacom stores and everytime they say I need to email , which I've done a few time an Noone absolutely Noone replies . Which is pathetic that a huge business does this to someone or anyone. But let u be a day late with payment then they quick to email an call you. As fast as you call or email why can't one get the same reaction when trying to lower or cancel 🤔. An if I stop paying then they want to send you lawyers letters for not paying . I'm extremely unhappy with the **** service an yes I say **** because I'm a paying customer .
