WORST SERVICE EVER!

This is the worst *********** service I have ever had. I requested and order a service for to be activated on the 27th of March as I still have a contract in place with my previous service provider till then and am required to give 1 calendar notice. My order took place in February - They then took it upon themselves to activate the service much earlier than requested and debited my account for a service that is not even in use. I then complained and reversed the debit order as I cannot pay nor use 2 providers at the same time. I have been struggling to have this sorted out sine beginning of the month to ensure that I have an active connection from the requested date. Instead I get a lame answer telling me that my previous service provider should refund me. This is unacceptable, I am responsible for the binding contract and fees for the Calendar month. I have requested cancellation of all services, but have not had any further response. I have tried the WhatsApp line, calling emailing even the original sales persons Nazeema, who just shrugs me off, its not her problem. I now show in arrears with them. This is what I get for being a honest citizen. Come get your router that I never ordered and was delivered anyway and cancel and reverse your invoice. Worst service ever!
