Supersonic negligence

I would like you to help with a problem with supersonic. We have a problem with our service. When you call or message there WhatsApp, they make you out to be stupid. Restart the route, then when the problem persist they don’t answer leaves you hanging, when I finally ask for a reference they pass me off to vumatel, they send a technician only to find that they say everything is fine , I need to contact my ISP. It looks to me like a ping pong game . We then call our ISP supersonic, the lady just gives you the standard “we will escalate the problem “ There is no care or sympathy or Drive to help with the problem, just blame shifting. This is the third time I have a problem like this and it takes 7 to 14 days for them to finally send a supersonic guy named John and in 5 min he solves the problem. I asked for the supervisor this time , I got left on hold for 10min and then got told a supervisor will call back, that was at 18:08 and it’s now 20:06 on the 14th March 2023. I run a business and my financial year end needs to be done and all my books are online , this ignorance and no care that supersonic is displaying is astonishing and not acceptable. They are in breach of contract, I pay my fees every month on schedule and have not to this day missed a beat but when it is time for my money to work, they make any excuse they can , in my book, they in breach of there contract with me and I need some one to fix this and quickly, as my lovely hood is at a stand still thanks to there ignorance.
