poor service

on'the 11th of october I decided to go ask to gym , thinking that my membership had been up to date with the payments. when I arrived the age advised me firstly that I do not even have a contract with them yet I had since the last 3 years. I then inquire if they could see on the system what was the issue, the said I needed to pay an amount of R2500, what amazed me more was when they said my account had been hand over without my knowledge. I called the call centre to speak to one of their consultants namely Richa Slamat, not very helpful in this regard, she said there was nothing she can do as it is my responsibility. my query though is I find it so difficult to comprehended why MY SERVICE PROVI DR could not contact me once if my premium was over due knowing fully what a long standing contract I have with them. It's all nice and rosey when money gets deducted from my account, they also hand people over so quick yet cannot make 1 call to clients advising them on their contracts. worst customer service and service provider I have ever experienced.
