poor knowledge between store and call centre

I have called the store and the call centre today in regards to a once off payment that i have made for both my contracts. Firstly the wrong acc details were given to me but rectified. From there on i called the call centre regarding the once of payment on two occassions two different agents said that they would get the team leader to call me back which never happend. Today i called the store and spoke to sachin from 8ta midlands mall which suppose to get back to which he didnt. I confirmed agn with paul from the call centre in which he says that he doesnt knw anything of a once of payment. I called the store and sachin says the call centre doesnt knw what they are doing. I am the customer, is there any knowledgable person that can sort my query. Why is there a poor communication btwn store and call centre. Why is there unreliable people stil working in such areas? I paid R6900 upfront to get such **** service? This is non sense. I will never refer anyone to buy from the 8ta store and the midlands branch. I also have the conversation recorded from the call centre and store <br>
