Rrustrated Rain Customer

I have cancel my rain data services because the network no longer fit my situation as I needed a stable connection for work purposes. Rain contacted me and convinced not to cancel and maybe get someone to take over the router and services. I agreed and gave my router to my cousin. The agent told me that I would pay +/-R850 at the end of the month and I advised the agent that the debit order should be going off at the 1st of every month because I have been getting at the 25th of every month and that is causing a problem for me with bank charges. Agent agreed that the account will be debited on the 1st of every month but that never happened, account was still being debited on the 25th of every month. month end I paid double my monthly installment of R595 a month. I paid R595.00 and just paid again R595.00 in case they cut my cousin's connection. The following month they try to debit my account with +/-R1147.00 on the 25th again so I called and asked them why are they debiting my account for that amount coz last month when I spoke to the agent we made arrangements for me not to cancel and to continue and the reconnection fee was 800 and something Rand and this month the normal rate will apply because I was being retained from cancelling my account. The story was totally different and they had no history of my account and arrangements to be retained. no knowledge of a retention officer calling me or anything and was adamant I owe over R1000.00 I immediately cancel and advised them to come fetch their router. No one contacted me to make arrangements to come fetch the router and now this month I am being debited 3 different amounts from rain. one amount is R1765.81 and another amount of R595.00 and another amount of R441.45 and all the the 25th of the month. these debit orders are messing up my credit rating and my bank charges. Dealing with this company is the worst experience of my life. I'm so tired of Rain. No one in the company knows what they doing and when you call in you land up speaking to rude people from India who hardly understand English.
