Did you give all money upfront??. We bought a round and I made up an agreement (not sure if it was actually worth it..lol, but just in case). We paid a deposit, and agreed that we wanted all customers numbers/adresses and would work the round for two months and introduce ourselves (which we did), and not canvass any and do a runner without paying.
In turn, the guy received no more money until we had established it and if we lost any, i.e they moved, got another cleaner, etc... we deducted this from the final payment. It worked fine.
If it is an honest round I honestly think it should be paid in instalments.
Another guy wanted it all upfront, and we said instalments....................funny, he decided not to sell it and have never heard from him again.
Really sorry to hear that m8
Hope it works out
