Bad customer service

Was at the Samsung Eastgate,took my phone in for repairs on the 21st of August And they told me it will take two days to be fixed.Fetched it on the 28th of August And the charging system was now working perfectly well to my surprise now the speakers weren't working.Took the phone back on the 29th and was told they will contact as soon as they have accessed it,That's a business line and it's an inconvenience for me worst part is the consultant was casual about it,no matter of agency nor customers service now I have to wait God knows how long for them to contact me.
