Disgusting, dishonest customer service

Good day I have a cellphone contract with MR P mobile for a tablet which was offrered to me at R99 pm. I took out the contract in September 2016. At the time of taking out the contract i specifically remember declining all extra offers that came with the contract due to knowing in advance that I would not be making use of the sim card. Since then i have been debited every single month R177.00. Upon various attempts with trying to fix this with their customer service this has still not been resolved. First time i called their systems were offline and they promised to call me back. They never did. I eventually called back and when i did this the customer service agent informed me that i had chosed extra offers with the contract. Once I informed the agent I did not they cancelled these options. I then requested for the telephone conversation as i wanted to be refunded for the amounts. More than a month late still no response from them. I eventually called back after being debited once again for an amount even more than the original R177. The manager never seems to be available and the agent whom i spoke to day advised me that should the call reveal that i did indeed decline those services I shall only be credited for the current month. I am not sure whether Mr P Mobile is aware what customer service means exactly but their agents have a ****py attitude cross questioning me about the time line when they have been giving me the run around. I would really like management from Mr P mobile to contact me to resolve this issue. Your site does not seem to be operational at this point in time hence me using Facebook. Regards
