Bad Service from Rain

I activated my sim from Clicks in September and ordered another pay as you go from rain which was promptly delivered and the sim was not in use and never been in use. I upgraded only one sim and left the unused sim on pay as you go. Rain then upgraded both the sims which included the pay as you go. I have corresponded on numerous times with them. Now I see on my account that both sims are due for a downgrade to pay as you go but no credit was passed on the sim that is not in use and for which was never upgraded although they say the issue is resolved. Its very bad service. if my issue is not resolved, I will have no option but to cancel my service. From the reviews I have been reading, I am not the only one that is having issues. I wish I had read the reviews before using the service.
