Bad bad services

I paid my installment but my internet was suspended,I have the proof of payment on my bank statement,I've send it to them via emails but they don't seem to attend to my cry out ,I've called them and all my airtime went to waste because it's answering machine,if so I want my money back for the humiliation they've put me through,They don't even value me ,I did pay them honestly to their Standard bank account,why did they suspend my internet while I was unaware that they couldn't see my payment,I'm so sad
