Such an unprofessional small business which cares less of its customers

My journey with simply wifi started earlier this month, there were no hustles in joining but the communication and customer service skills have been unacceptable and horrible. First they took time to register my preferred password, and give me the fibre speed which corresponds with the package I had paid for, taking them over a week to amend this. On the 7th of March I requested for assistance so that they can organise a way for me to get a fibre box which will be connected onto an inverter for me to be able to make use of the fibre even during load shedding, they have not only been giving me a run around but each week they say they'd respond and give me feedback the following week. Its almost a month now of waiting without any assistance. As a paying client I don't believe this is the treatment I should be getting. They are highly unprofessional and I definitely wouldn't advise one to make use of such services.
