Disappointed

I changed my payment date in May and have been issues since. I was adviced that I owe in June and advised by a manager that this is sorted, I then spoke to another manager in July and was advised I still owe a balance even though the first one told me this is a systematical issue, I then checked my wifi on the 15th and it went off because apparently I missed a payment for July, even though I was advised to send my POP, I did this on the day, I called in the Friday again to Friday out what the next steps will be as no one got into touch with me and I advised the agent in the next 24 to 72 hours I will get feedback, it's been two weeks that I'm without wifi I work from home and this is a struggle cause management is up my ass, I work and I had to loan money to buy data to work, no one will compensate me for that money that I gave out for airtime to call you guys for the money I had to loan to pay for data to work or unpaid days that I will be receiving at work, rain is going to want the full payment of this month when it's due no one will be compensating me for the days I have been off, this is disgusting service cause whenever I call in all I get told is I need to wait until the billing team gets into touch with me, managers and agents have been emailing them and no one has gotten in touch with me, I did not expect this from rain I've been a customer for years
