Bad Service and Laid back attitude

I have a membership with this gym and they are not settling my account that is in arrears I made a payment 2nd of October 2017 for the August fee into the bank account, gave the proof of payment to a lady at the branch and she said she will sort it out.. Month end of a October my account was debited three times whereby it was suppose to be only 2 debit orders.. I emailed my proof of payment to customer service on the 30th of October 2017 they received it and gave me a reference. . The Wednesday I went to the gym to use the facilities got there and my tag declined to enter so a consultant said my account is in arrears and I told him I paid emailed the customer service. He said he can't do anything as I need to deal with them directly.. No help what so ever.. On Thursday I called customer service they said it's pending at the administration department they will call me in 72 hours.. No one has called me.. Went to the gym on the 4th of November they told me my account is still blocked. . Highly upset as they still could not assist me.. on Monday the 6th I called customer service they than transferred me to Newtown to the administration lady but another lady named Quinn answered and I explained to her my situation she said she cannot disturb the administration lady as she is busy with banking she will let the lady call me, no one called me.. On the 7th I called customer service again they put me through to Newtown again I spoke to a gentleman named TK he was helpful after me arguing with him he gave me his email address to email the proof of payment which I did and said he will get back to me which he did saying he handed it over to the administration lady and waiting for her to get back to him.. The 8th of November I called Newtown directly and Quinn answered I asked for TK she said he won't be in due to the strike so I explained to her once again and all she cab say is I understand your frustration I mean really what laid back attitude.. she checked my account it's still not cleared I told her I will be taking further action now and wanting to cancel my membership as it cannot take 2 weeks to clear.. She was not helpful told me she will speak to the administration lady I told her I have been hearing this from Monday this lady cannot have the decency to call me and tell me she is handling it.. my account up until now is blocked and no one seems to be giving me the help I need and now I cannot use the gym facilities. . This is ridiculous and complete disgusting service. I have been a loyal client and this is what I get on return.. Highly upset
