Supersonic and Vumatel

I made a payment 25th of April 2025 but my fibre router is still offline I've called Vumatel several times about this matter and they told me I must call my ISP which is Supersonic and called Supersonic for a number of times and they told me to send the proof of payment of which I did and after that each and every call I make to them they tell me they have escalated the matter to Vumatel because my payment was not allocated to my account but it was wrongly allocated by them to someones account I even want to Vumatel branch in Melrose Arch and they told me they will resolve the matter in minutes time but nothing happened I've been waiting since the 25th for them to allocate it today is the 5th of May 2025 still waiting for them to allocate my payment and I'm still offline 😡
