Poor Customer Service

Hi I purchased router with Rain and everything was okay and the agent explained to me that if I don't pay for the month I will have no wifi as it is month to month and it doesn't have any penalties, it was delivered so I requested to take the another router for somebody else and explained to the agent who was assisting me and everything was fast as it was towards the end of business day... So I asked him now that you did not take or ask for the details of the person to be billed for the new router won't it be a problem? He said it won't and come month end the bill was added under mine... I tried to contact them they never got back to me so I decided not to pay They called me with the promise to pay plan and I did that and it was active for the following month... When I logged in under my account I saw that the bill has been accumulated to my surprise and I requested the second router cancellation and was given ticket number and no one got back to me until now when they see that I decided not to pay I explained everything to them and they said it will be canceled then I need to pay new promise to pay of which I did on the 19th of November twice and still the wifi is still inactive when I contact them they send me from pillar to post... I never experienced such poor customer service before... Rain has got the worst customer service... I spoke to more than 5 agents and all of them have been given me different explanations and I don't have their names the ones I remember I Linda and Leila... I really am exhausted by the service I received from rain... Really how do I pay for service that I didn't receive or use as they told me it's not a contract. As for the promise to pay it was paid at 12:31 in store and when I asked why is it still not active they said the link has expired and I explained to her that I can only do payment in store as there are no funds in my account and she said there is no problem I can pay in store so I did that and still the same thing happened when I enquired the other agent said I was supposed to pay using a link of which the link has the pay in store option. As I asked for the amount paid to be re allocated as PTP she said they are unable to do that... I really do believe that Rain sucks a lot. Their staff are not trained.. They all say different things which inconvenience us as clients.
