Pathetic customer service

On the 14th of February I settled my loan account I had with Standard Bank since 2011, the branch manager Sean Kemp from the Tygervalley branch assisted me.I explained to him that i have a concern wrt my balance on the loan .He checked on the pc and said something does not look right and that they will do an investigation, I was promised a call phone the Monday but to no avail I tried calling and eventually on Wednesday got Sean's email address- He responded and said they have requested my contract, this past Saturday i went to the branch and still no body was able to assist me.I am getting abit impatient as since Monday i have sent emails to Sean and has had no response.I will be taking this further and I will make sure that everybody knows who Standard Bank treats their customers.Standard Bank got their money and now they dont care.
