****ty service and stupid agents

I have a runninh 20/10 mbps speed. I needed 100/50 for work. Spoke to an agent and asked if it would be possiblw to do an upgradr immediately and she said. If I do not minde losing the days I have left on the 20/10speed. I agrees to lose the days. She gave me a new easypay number and I paid for the new speed. She then told me she has escalates this and it should be sorted withinh 48hours. The new speed will be activated. 48hours later nothing has been done I contact them on whatsapp I get another agenr who tells me, I was **** to. The cancellation was scheduled for a later date and there is nothing they can do. Now I am stuck here and cannoy work because the speed was not upgraded as agreed and apparently this was done incorrectly on their side. No one wants to take ownership of the error and fix it. Such bad customer service. I am told they cannot fix the issue so **** me!. I want my money back and I am told it will take 30 days. So what must happen now? I never requested for a scheduled cancellation If that was the case. I was going to go else where and not pay.
