Quick response then left hanging

Contacted call center just now to find out to track a overseas payment and was impressed with the quick and professional response by the 2 consultants who put me through to the relative dept. However sadly and most frustratingly on the 3rd time of being put through to another Consultant the call was answered and all I could here was constant ****led talking i.e. Amongst the other call center reps or customers. After a while I discontinued the call as there was no way of getting back to the main menu. I have tried 4 times to contact them again and have no time to try and sort this out. Please can someone assist me?
