Horrible customer service

Supersonic customer service is pathetic. I have logged an issue for speed to be dropped on their site that it will takes 3 days for it to change , this was on the 26 of February and now it will only be dropped in May. I have also requested the same month for cancellations due to relocation and it was not allowing on their site and you have to give a month notice of cancellations , I have requested a ticket regarding this too and have sent emails to them . During March I asked for follow ups by the agents on WhatsApp no responses. Nobody got back to me calls or emails . I have tried calling customer care line nobody picks up. Today went online to check the tickets , it showing that they have closed my tickets without any assistance .
